Orthogonal Frequency Division Multiplexing (OFDM) is a modulation technique that uses a large number of narrow-band subcarriers instead of a single wide-band subcarrier to transmit data over non-flat fading channels. OFDM is the preferred mode of modulation in WiFi and LTE standards. OFDM requires sending data over a wide range of frequencies, i.e. the channel has a large bandwidth, as represented in Figure a. A large bandwidth of the channel implies a frequency-dependent frequency response of the channel. To assume a flat-fading model for efficient calculations, the carrier signal is divided into parallel strips of subcarriers each having equal coherence bandwidth, as shown in Figure b. This flat-fading model provides advantages like simpler implementation, robust performance, and sharply reduces the chances of frequency-selective fading. https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1620687163635-ZYA4PWD8DY5MKU5SMCUU/Lab+3A_Cyclic+Convolution.jpg Portfolio - DIY WiFi - Tx: Cyclic Convolution The first step of OFDM involves encoding the the signal to be transmitted using the Inverse Discrete Fourier Transform (IDFT). In real-world implementations, this IDFT is performed digitally, which means that a circular convolution must be performed to move data from the frequency domain into the time domain. However, a perfect IDFT requires infinite extension of the signal in both directions. For a symbol of length L, with M bits long impulse response, and M < L, this problem is solved by selecting the last M-1 bits of every symbol, and repeating them in front of the symbol to create an illusion of infinite symbol extension. Those M-1 bits of data are called Cyclic Prefixes (CPs); CPs help reduce the inter-symbol interference (ISI) and reduce computational runtime by quickly converting a linear convolution into cyclic convolution. https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1620704676967-E3X1E18AQVZ8QQXFW5QB/channel-estimation.png Portfolio - DIY WiFi - Rx: Channel Estimation and Equalization Channel estimation and equalization was performed using Least Squares Error (LSE) algorithm. LSE estimation involves dividing the received data of a known transmitted symbol by the corresponding received data point. The image on the right shows the linear algebra behind channel estimation for a two-antenna system. Accuracy of LSE can be improved by increasing the number of OFDM symbols being sampled and performing element-wise division to compensate for noise. For my implementation, I sampled the channel estimate over 12 symbols. https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1620705617483-G86727P930PB1Y4YF6YE/xcorr.png Portfolio - DIY WiFi - Rx: Timing Synchronization Cross-correlation of the preamble with the received signal was used to predict the beginning of the received signal. This functionality was provided by the xcorr function in MATLAB, which also returns the lags at which the index of the cross-correlation is highest. https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1620706886119-EN282GIVLT6FYYSQ4N1H/schmidl-cox.PNG Portfolio - DIY WiFi - Rx: Carrier Frequency Offset Correction The Schmidl-Cox algorithm was used to implement Carrier Frequency Offset (CFO) correction. For a signal that has been temporally-synchronized, CFO correction using Schmidl-Cox can be implemented by summing the result of the division of the angle of subcarrier n by the angle of subcarrier n+L, where n is the index and L is the length of a symbol. Next, this sum is divided by the total number of subcarriers in a symbol, i.e. L, which gives the frequency offset f. CFO is performed by taking the exponent of f*[k]*(-j) and multiplying it with the received, temporally-synchronized signal. Here, k is the sample number and j is the complex number iota. https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1620700677650-VQSDRB9G8NSJ33LUXZGQ/Lab+3C_OFDM+Transmission.jpg Portfolio - DIY WiFi - Rx: Phase Offset Correction (Pilot) and Guard Bands Phase offset compensation is needed to correct for drift in the oscillations of the Tx and Rx crystals. In WiFi systems, CFO correction is performed per packet of data while phase correction is performed per OFDM symbol. 802.11a standards use 4 pilot symbols at index locations -21, -7, 7, and 21. Our implementation divided data the 48 data subcarriers into an even split of 6, 12, 12, and 6 subcarriers, thus moving the location of pilots to -20, -7, 7, and 20 in Figure c. Additionally, 802.11a specifies guard bands equal to 11 subcarriers with 6 at the beginning and 5 end of each symbol to decrease ISI and reduce spectrum spread from adjacent subcarriers/symbols. The guard bands can seen in Figure b and Figure c. Finally, a null is placed at the center of the symbol which corresponds to the DC subcarrier. This subcarrier is not used for carrying data because the Rx local oscillator leaks into the DC component of the OFDM symbol, rendering it useless. https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1620691203649-ZJAQMH8HV2V4897H5F0I/3C_Scatter_4Mbps.png Portfolio - DIY WiFi https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1620691186560-YHX1528IXUR80199QOJ2/3C_Scatter_2Mbps.png Portfolio - DIY WiFi https://utsav22g.com/portfolio/archived/kitty-caddy monthly 0.5 2023-09-27 https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1607920652892-RZKSZKAYGY2F3NQSB0A6/Real-World-Controller.jpg Portfolio - Kitty Caddy - Problem Statement Design and build a real-world controller using modular components. Chosen project should integrate a microcontroller with special-purpose modules for power regulation, motion control, graphical display, audio generation, digital radio communication, or environmental sensing along with the software needed to control them. An additional area of study (like mechanical integration, user interface design, etc.) should be chosen by the student. https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1607921139868-ZMKDHYQAVVJ8774FH7KZ/SMT.jpg Portfolio - Kitty Caddy - Surface Mount Technology I chose Surface Mount Technology as my additional area of study. Rather than using modular, over the counter packages like Arduino Nano as a microcontroller, I chose to layout the ATmega328P. I also implemented a custom circuit for the 12V to 5V buck converter using a TI chip. A complimentary constraint due to the limited space in the Kitty Caddy chassis was size of the PCB; hence I used a 4 layer PCB layout for an easier layout and routing. https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1607914021419-FVKT7VRJEOCDO0HIZL1D/Schematic.PNG Portfolio - Kitty Caddy https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1607930520890-VS5KW4NN06KHBJ4S6DQ1/Top+Layer.PNG Portfolio - Kitty Caddy https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1607930598520-LP1A3CO0UEO6HKJUADNW/Bottom+Layer.PNG Portfolio - Kitty Caddy https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1607930560402-LC4015CC23RFR11FETCS/Inner+Layer+2.PNG Portfolio - Kitty Caddy https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1607930545675-4D81RMB3V8YD4YLNACKB/Inner+Layer+1.PNG Portfolio - Kitty Caddy https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1607923048379-WXPBDOBTXMZCF5LS14RX/Kitty_Caddy_Back.jpg Portfolio - Kitty Caddy https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1607923103968-ZLXYDA04E9PO9FTPGZIA/Kitty_Caddy_Front.jpg Portfolio - Kitty Caddy https://images.squarespace-cdn.com/content/v1/5e3e2bed94d5fa3ebbab7a70/1607923584603-YSP7EBXDAQ2EPWZ5KOP8/Kitty_Caddy_Final.jpg Portfolio - Kitty Caddy - Final Deliverable The image on the right shows the final version of Kitty Caddy.
