Samenvatting

Repetition-based retransmission is used in Alamouti-modulation [1998] for 2 times 2 MIMO systems. We propose to use instead of ordinary repetition so-called dasiascaled repetitionpsila together with rotation. It is shown that the rotated and scaled Alamouti code has a hard-decision performance which is only slightly worse than that of the Golden code [2005], the best known 2 times 2 space-time code. Decoding the Golden code requires an exhaustive search over all the codewords (or sphere decoding for higher spectral efficiencies), while our rotated and scaled Alamouti code can be decoded with an acceptable complexity.
