Table-based bit-interleaved coded differential APM scheme for correlated fading channels
Communications in China（2014）
摘要
In this paper, we investigate the design procedures of the bit labelling rule as well as the outer channel code for the table-based bit-interleaved coded differential amplitude/phase modulation (BICD-APM) scheme under correlated Rayleigh fading channels. Based on the asymptotic pairwise error probability (PEP) formula reported in the previous work, the design criteria for the generator polynomials of the outer convolutional encoder, and for the bit labelling strategy of the inner differential modulator, are investigated for the table-based differential APM schemes when considering two different types of bit interleavers. It is shown that the designed scheme which considers parallel bit interleavers is able to achieve the best bit error rate (BER) performance, and provides a significant SNR gain under the same BER value, when compared to the conventional BICD-APM scheme reported in the previous literature.
