EE 567 Matlab Project #1 Due Date: Friday, October 8 th at 5pm in EE 567 dropbox near EEB 114 Problem: In this project, you will build a digital communication system in Matlab that implements the transmitter, receiver, and AWGN channel. You will develop sample-based simulations as compared to symbol based simulations. That is, the transmitted symbols must be oversampled to provide adequate time resolution. You will generate results for BPSK, QPSK and 8-PSK waveforms. You must implement the following functional blocks: (1) Random bit generator (2) Symbol mapper (3) SQRC matched filters (4) Additive noise generator (5) Symbol detector (6) Inverse symbol mapper (7) Probability of error (BER) calculation The symbol rate is 1 Hz, so one symbol per second. The sampling rate is 16 times the symbol rate. Thus, the sampling rate, f s , is 16 Hz. PART 1: (1) Implement the simulation blocks using equally probable binary data (p = 0.5) and plot the waveforms of the first 16 symbols after each stage for BPSK for the noise-free case. (2) Using the data (p=0.5) perform simulations to plot the probability of error (BER) versus E b /N o for the BPSK modulation using the ideal matched SQRC filters. The range should
