Blind decoding and channel estimation algorithms for vertical layered space-time coding
Yanxing Zeng · Journal of China Institute of Communications · 2004
The blind algorithms for symbol detection and channel identification were proposed in the vertical bell lab's layered space-time coding (VBLAST) scheme. By introducing the pre-coding, a new VBLAST scheme was proposed so that both the original transmitted symbols and the channels can be estimated via an ESPRIT-like method. Furthermore, this scheme can also eliminate the constraint that the number of receive antennas must be more than transmit ones, which is necessary in the most proposed symbol detection and channel identification algorithm. Computer simulation results show that the proposed algorithms have the similar performance with the non-blind ones.
