Blind MIMO using the Golden code

The Golden code has been proposed as an optimal space-time code for multiple-input multiple-output (MIMO) communication systems. This paper considers a ¿blind¿ MIMO system where the channel is assumed to be unknown. The Golden code is unidentifiable under this condition and can not be used directly. A block code modification is described which makes the Golden code usable in the context of blind joint symbol-channel estimation. A suboptimal receiver with modest computational requirements is presented and the performance of the blind system is illustrated.
