WebbThe exact expression for the probability of a packet error is derived for both DPSK and DE-BPSK. It is shown that ignoring the paired error tendency and using the simpler independent bit error assumption yields an upper bound which, for large packet sizes, is in error by no more than approximately 0.1 dB for DPSK and 0.2 dB for DE-BPSK. Webb10 feb. 2024 · SNR is well known measure of how the signal and noise power compare against each other. It directly affects the probability of error performance of a system.
