Bit-Error-Rate Analysis of Raptor Codes over Rician Fading Channels

Bit-Error-Rate Analysis of Raptor Codes over Rician Fading Channels

The bit-error-rate expressions of nonsystematic Raptor (NR) codes and systematic Raptor (SR) codes over Rician fading channels are first derived using a Gaussian approximation (GA) approach. These BER expressions provide a significant reduction in computational complexity for analyzing system perfor...
