Symbol error rate for BPSK, QPSK and QAM in Rayleigh channel

Contributed by Jean-Paul Linnartz and Haibing Yang

This spreadsheet allows you to interactively experiment with the effect of fading. The channel model is Rayleigh fading. See also the spreadsheet for BER with Ricean fading.

BER in a Rayleigh fading channel

Input parameters:

Energy per subcarrier over spectral power density of the AWGN. Used for SER calculation.

Results for SER

BPSK uncoded
QPSK uncoded
16-QAM uncoded
64-QAM uncoded
