摘要：
The performance of a BICM-ID system with multidimensional (MD) modulation is investigated. Design criteria of MD constellation labelling are proposed and BICM-ID schemes with QPSK of different dimensions are established. Simulation results show that when each data block contains 50 000 information bits and the iteration number is 20, the BER of BICM-ID with six-dimensional QPSK and four-state rate 1/2 convolutional code is 10(-5) at SNR = 0.9 dB over an AWGN channel which is only 0.2 dB away from Berrou's turbo code.
