ABSTRACT:
A system and method to transmit and receive forward error corrected data in a diversity communications system is provided. Using diversity techniques, multiple copies of the transmitted data are received with varying degrees of corruption due to channel impairments. In addition to the multiple copies of forward error corrected data, an additional data set of implicit parity bits is used in the data decoding process, wherein the reliability of these parity bits is assumed to be very high. The implicit parity bits are not transmitted or received by the system, but are introduced in the receivers' decoding process. These implicit parity bits add an extra highly reliable dimension of forward error correction codes. Therefore the present system and methods provide an improved data decoding process with high coding gain and channel efficiency, while minimizing system resources.
