Method and system for error correction in transmitting data using low complexity systematic encoder |
摘要 |
A systematic encoder such as a systematic polar encoder for channel encoding to ameliorate the effects of noise in a transmission channel. The codeword carries a data word to be transmitted transparently, and also carries a parity part derived from the data word and a fixed word. Implementations advantageously reduce coding complexity to the order of N log(N), wherein N is the dimension of a matrix of the nth Kronecker power associated with a matrix effectively employed by the encoder. |

1. A systematic encoder assembly of low complexity comprising:
input receiving data symbols sought to be transmitted; the assembly accessing at least one fixed word that does not change from transmission to transmission; circuit receiving the data symbols and the at least one fixed word and using at least portions of the data symbols to define at least systematic parts of code words; the circuit using at least portions of the fixed word to define at least a fixed part of an input word, the input word establishing at least in part a parity part of a code word; and the circuit outputting, for transmission, code words transparently encapsulating data symbols and including respective parity parts a transmitter receiving the code words and transmitting the code words through a transmission medium to a receiver. |
