Abstract :
We design a family of fast-decodable, rate-unbalanced space-time block codes (STBCs) for 4 × 2 multiple-input multiple-output (MIMO) transmission. These codes are generated by combining Alamouti and Silver codes into two layers. Their low-complexity decoder does MMSE successive interference cancellation (SIC) and sphere decoding. As shown by computer simulation, the proposed codes exhibit a better performance than equivalent diversity-embedded and groupwise STBCs, and yet have an intermediate decoding complexity.
