| 抄録: | In this paper, a very simple close Shannon-limit achieving Bit-Interleaved Coded Modulation with Iterative Detection/Decoding (BICM-ID) system is proposed. The irregular repetition and single parity check codes, combined with partial accumulator and Extended Mapping (EM) are used. This paper also proposes EXIT-constraint Binary Switching Algorithm (EBSA) to determined optimal labeling patterns for allocated to each constellation point. With the proposed technique, the Extrinsic Information Transfer (EXIT) functions of the demapper and decoder curves can be closely matched. Furthermore, this paper combines the techniques described above together with modulation doping. It is shown through EXIT analysis that the demapper and decoder EXIT curves closely matched, and therefore, very near-capacity performance can be achieved. Bit Error Rate (BER) simulation results show that using our proposed technique, at a signal-noise ratio (SNR) point of only roughly 0.5dB away from the Shannon limit, clear threshold SNR happens, even though required complexity is very low; the complexity of the proposed technique is at an order of that required for a turbo code using memory-2 convolutional constituency codes. |
