HARQ Scheme for MIMO Systems with Antenna Selection

A new type hybrid automatic repeat request（HARQ） scheme based on orthogonal space-time block code（OSTBC） is proposed and evaluated in multiple-input multiple-output（MIMO） systems.The transmit antennas are selected based on the feedback from the receiver.The modulated symbols are encoded by spacetime...

Summary:A new type hybrid automatic repeat request（HARQ） scheme based on orthogonal space-time block code（OSTBC） is proposed and evaluated in multiple-input multiple-output（MIMO） systems.The transmit antennas are selected based on the feedback from the receiver.The modulated symbols are encoded by spacetime block code（STBC） and obtained by space time code blocks which are suitable for the number of selected antennas.The total packet error rate（PER） is given by defining the decoding function and the best value of the maximum number of HARQ retransmissions is discussed.Theory and simulation results illustrate that：this new HARQ scheme with antenna selection method has lower PER and the result is also satisfying.
