Analysis of the simulation
When we transmit any data without any coding by AWGN, Rayleigh or Rician fading channel then it needs very high SNR to receive it and has very bad error performance.
The channel performance for uncoded data transmited over awgn, rayligh, and rician channel. Here we find that awgn channel has the best performance and rayligh fading channel has the worst. But in satellite transmission rician channel is generally considered for line of sight (LOS) communication. For bit error rate 10-5 the bitrate according to SNR.
