A Combination Scheme for Serial Turbo Code and Differential Unitary Space-Time Modulation

摘要：

When channel state information (CSI) is not available, in a continuous fading channel, combined differential unitary space-time modulation and parallel turbo code can greatly improve the system performance, however it also meet with the error floor phenomenon. We propose a scheme of utilizing differential unitary space-time symbol-based serial turbo code for multiple-antenna wireless communication systems over continuous fading channels which can avoid the error floor. We also give the MAP decoding algorithm and its simplified versions for both the systematic symbol and the parity symbols. With iterative decoding and/or multi-antennas, it can further improve the system performance, which helps to give an acceptable bit error rate.
