Efficient-BER-computation-of-LDPC-coded-SC_MRC-sy
Abstract—Selection combining cascaded with maximum-ratio
combining (SC/MRC), which is particularly useful when site
diversity is available, combined with low-density parity-check
(LDPC) codes is able to combat the effects of fading. The biterror
rate (BER) expressions of uncoded SC/MRC and SC/MRC
with LDPC codes over an independent and identically distributed
Rayleigh-fading channel are derived based on the Gaussian
approximation approach. These expressions are also applicable
to the selection combining and maximum-ratio combining as
special cases. The derived expressions are in good agreement
with simulation results and approach the density evolution (DE)
thresholds. These expressions are able to achieve a significant
reduction in computational time with a reasonable accuracy for
analyzing the BER performance as compared to simulations and
DE.
