6.3 Using Matlab, write two functions that compute the bit error probability of MRRC and Alamouti systems in Rayleigh fading using BPSK modulation. Call these functions MRRC.m and Alamouti.m. Each of these functions should compute the BER using both Monte Carlo simulation techniques as well as the theory given in Eq. 6.33. Use these functions to duplicate Figure 6.5 6.3 Using Matlab, write two functions that compute the bit error probability of MRRC and Alamouti systems in Rayleigh fading using BPSK modulation.
