MIMO iterative decoding of serial concatenation using space-time trellis codes

Serial Concatenation of Space-Time and Recursive Convolutional Codes

“…Simulations for two transmit and one receive antennas in a quasi-static, flat Rayleigh fading channel show that the new scheme gives significantly better performance than the original multiple coding/separate decoding scheme [4]. As compared with joint decoding [6], the new scheme proposed in this paper achieves slightly better performance, while maintaining a lower complexity.…”

“…In conventional error-correction coding for single-antenna communication systems, the concatenations of two convolutional codes with an interleaver in between, known as "turbo codes," provide a significant coding gain [3]. Recently, several concatenation schemes have also been proposed for multiple-antenna systems [4]- [6]. A serial concatenation proposed by Lin and Blum [4] employed a space-time code as the outer code and multiple recursive convolutional codes as the inner code.…”

“…A serial concatenation proposed by Lin and Blum [4] employed a space-time code as the outer code and multiple recursive convolutional codes as the inner code. They used a separate decoding scheme for each multiple inner code, whereas Yim et al [6] used a decoding scheme which jointly decodes all the simultaneous output symbols from the inner encoders. No direct performance comparison has been made between the two decoding schemes.…”

Simple design method for space-time trellis codes with and without serial concatenation

“…They were optimized for the quasistatic flat fading channel. Numerous papers have given improved codes [2]- [5] and concatenation schemes [6]- [9] for improving performance on MIMO fading channels. As much diversity exists for MIMO channels, the performance criterion for optimization in our design method will be the Euclidean distance criterion (EDC) rather than the rank and determinant criteria (RDC) [l].…”
