Adaptive Code Combining Algorithms for Hybrid ARQ System Based on Low Power PLC
Wenling Xue · Journal of Hebei University · 2006
An algorithms of code combining for hybrid ARQ is presented.In order to end the resending process as quickly as possible,the algorithms adopts a strategy sending the same date R times in one resending frame,and R is increasing with the sequence number of resending.The second,a method to estimate the probability of decoding mistake is given.Using the method the probability of decoding mistake can be estimated and be controlled under a given level.So the credibility of decoding can be ensured.The algorithms is simple,efficient and adaptive to the changing of channel,there for is suitable to the systems with unstable channels,such as the low voltage power line carrier system.
