Joint Probability-algebraic Decoding for Tail-biting Codes Uused in LTE System |
| |
Abstract: | ![]() To fully make use of the information on the algebra structure of the tail-biting codes,we com-bined the WAVA algorithm with the algebraic decoding,and propose a new joint probability-algebraic decoding algorithm. Simulation results show that,compared with the single probability decoding,the new algorithm has better performance on the error correction. |
