Paper Abstract

Turbo codes and Low Density Parity Check (LDPC) codes are well known to provide Bit Error Rate (BER) performance close to the Shannon capacity limit. Bandwidth constrained satellite channels could potentially benefit by employing higher order PSK modulations. However, employing higher order PSK modulations may not be practical for satellite amplifiers due to the increased power requirements. The excellent performance of serial concatenated turbo codes could be used to maintain satellite amplifier power levels to those relatively close to the Shannon limit. The performance of the system, however, is dependent on the satellite channel, which typically includes phase noise and some degree of nonlinearity in the satellite amplifier. The performance of various waveforms and PSK modulations employing Serial Concatenated Turbo Codes are investigated using a model of a non-ideal satellite channel. The hardware complexity of the serial concatenated turbo decoder at the ground receiver is also considered.
