Abstract :
Proposed is a multiple automatic repeat request (ARQ) scheme for the MIMO channel adopting the structure of space-time block codes (STBCs). With multiple transmissions accompanied by the proposed combing strategy, the input-output relationship of the Alamouti STBC is formed in the receiver. It is observed that the proposed ARQ scheme attains higher throughput than others at all SNR values.
