Question: [Binary Symmetric Channel Capacity] Binary data are transmitted over an additive white Gaussian noise channel using BPSK signaling and hard-decision decoding at the output using optimal matched filter detection.
1. Plot the error probability of the channel as a function of
γ = E
N0
where Eis the energy in each BPSK signal and No/2 is the noise power spectral density. Assume that y changes from -20 dB to 20 dB.
2. Plot the capacity of the resulting channel as a function of y.
