Method communication system and phone for systematic encoding and computationally efficient decoding for minimizing error propagation

摘要

The present invention provides a method (600), phone (209), and communication system (202) including a systematic encoder (204) adapted to receive input data signals having a first plurality of data bits and generate encoded data signals having the first plurality of data bits and a first plurality of parity bits, a receiver (206) adapted to receive the encoded data signals and to generate values defining the encoded data signals, a decoder (208) coupled to the receiver (206) and adapted to generate a second plurality of data bits in response to the values defining the encoded data signals, and a post-decoder circuit (210) coupled to the decoder (208) adapted to receive the second plurality of data bits and for transforming the second plurality of data bits into an estimate of the first plurality of data bits.
