Abstract | Bit-interleaved coded differential space-time modulation (DSTM) for transmission over flat Rayleigh fading channels is discussed. For improved noncoherent detection without channel state information at the receiver, iterative decoding employing hard-decision feedback and prediction-based metric computation are applied. The performance is assessed based on analytical expressions for the bit-error rate and simulations. For the most relevant case of two transmit antennas, it is shown that the proposed scheme offers high power efficiency exploiting both space and time diversity, while computational complexity is kept at a low level. |
