Golden code is one of the algebraic space-time codes, which has the full rate, full diversity with the better performance than other codes. Sphere decoding (SD) algorithm can achieve near ML performance with moderate complexity. We proposed the modified complex sphere decoding algorithm based on Schnorr-Euchner strategy (SE-CSD) including sorting the order of the system that can reduce the computational effort than general sphere decoding algorithm over the range of SNRs. Combining Golden code with low complexity SE-CSD can obtain perfect performance than other solutions.
