摘要：
A space-time block code construction is presented which achieves maximum diversity for multi-antenna transmission. The construction is based on selected cyclotomic cosets of an extension field which are multiplied together to give a set of transformation polynomials. A space-time factorization code [1] can be constructed by encoding the information vector by different polynomials to form a set of codeword matrices. Codes are constructed over the Galios field GF(2) and mapped to the BPSK signal constellation. The effect of this mapping on the code design criteria is investigated. Simulation results are compared with the statistical properties of the codes based on the design criteria from [2] and [3].
