摘要：When channel state information is not available, combined unitary space-time modulation and parallel concatenated convolutional code can greatly improve the system performance, however it also meet with the error floor phenomenon. We propose a scheme of utilizing unitary space-time symbol based serial concatenated convolutional code for multiple-antenna wireless communication systems over rapid fading channels which can avoid the error floor. We also give the MAP decoding algorithm 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.
