Golden code is one of linear dispersion space-time block codes (LD-STBC), which has full rate, full diversity with better performance than other codes. sphere decoding (SD) algorithm can achieve near ML performance with moderate complexity. We propose the complex sphere decoding algorithm based on Schnorr-Euchner strategy (SE-CSD) needing no initial radius and it is implemented without a nodelist enjoying more complexity savings than general complex sphere decoding (CSD) algorithm over the range of SNRs. Combining golden code with low complexity SE-CSD can obtain perfect performance than other solutions.
