| Abstract(in English) | Recently, Rate-Compatible LDPC (RC-LDPC) codes are attractive research topics on channel coding. RC-LDPC codes provide various coding rates and users can select suitable code rates according to channel conditions. However, RC-LDPC codes have a disadvantage that transmitter should notify the code rate to the receiver as a side-information. In this paper, we proposed a rate estimation technique that the receiver can estimate used code rate based on posteriori log-likelihood ration (LLR) even if transmitter selects code rates randomly. Computer simulation results show that proposed technique can improve performance of rate estimation of RC-LDPC codes. Moreover, it is obtained that complexity of computation can be reduced. |
