This paper presents how to design Quasi-Orthogonal Space Time Block Coding for multiple transmitting antennas and one receiver with feedback. Multipath wireless environment creates difficulty because of diversity at multiple receivers and multiple transmitters. Diversity is reduced by using Quasi-Orthogonal STBC. For simplicity we considered four transmitters and one receiver. The diversity is achieved by reducing the non-zero off diagonal terms of quasi orthogonal matrix and by reducing thedoi:10.17812/ijra.1.3(23)2014 fatcat:fwamz3h62febbb3cnswzetlhgq
