Recently, Rate-Compatible LDPC (RC-LDPC) codes have become attractive research topics on channel coding. RC-LDPC codes provide various coding rates and users can select suitable coding rates according to channel conditions. However, RC-LDPC codes have a disadvantage: the transmitter notifies the coding rate to the receiver as side-information. In this paper, we propose a rate estimation technique which can estimate the rate with the Log-Likelihood Ratio (LLR) only, and have made performance comparison with two rate estimation techniques when transmitter selects coding rates randomly. Computer simulation results show that proposed technique can improve performance of rate estimation of RC-LDPC codes. |
