BPSK SYSTEM SIMULATION
We simulate the generation of random variables r0 and r1, which constitutes the input to detector. We begin by generating a binary sequence of 0?s and 1?s that occur with equal probability and are mutually (statistically) independent. For this, we use a Random number generator that generates a uniform random number between 0 and 1. If the number generated is in range (0, 0.5), the binary source output is 0 else it is 1. if 0 is generated, then r0=E+n0 and r1=n1. if a 1 is generated r0=n0 and r1=E+n1.
The additive noise components n0 and n1 are generated by mean of two gaussian noise generators there means are zero and there variances, doDl2 = E*N0/2. For convenience we take E=1(normalized value) and vary doDl2 . The SNR (E/N0) is then equal to 1/2doDl2. The detector output is compared with the binary transmitted sequence and an error counter is used to count the number of bit errors.
