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

open access: yesJournal of Electrical and Computer Engineering, 2020
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.
