Abstract :
The Alamouti space-time code for transmission diversity is extended recursively to 2n × 2n antenna elements as well as to unsymmetrical arrays of size m × n. The proposed schemes exhibit two significant advantages: they allow for higher diversity (of degree 2n for the symmetrical case) and at the same time can be implemented as zero-forcing or MMSE type at low complexity avoiding any matrix inversion due to the structure in the transmission matrices as well as low complexity ML.
