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 comprising:
a machine-implemented circuit establishing a systematic encoder encoding data words into code words and having a complexity of no more than 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, the encoder transmitting the code words as robust representations of the data words to a receiver system for retrieval of the data words from the code words by the receiver system wherein the encoder receives a data word d as an input signal sought to be transmitted and encapsulates the data word in a code word x such that the data word appears transparently in the code word, the code word being transmitted. |
