A low computational complexity differential detection scheme for Multiple Input Multiple Output system is proposed which is based on the full rate quasi-orthogonal space-time block codes.The transmitted bits are jointly mapped to construct quasi-orthogonal space-time block codes and the codes are used to perform differential encoding.At the receiver
Maximum Likelihood (ML) criterion is used to differentially decode the symbol pairs.The constellation set and joint constellation mapping defined in this paper simplify the detection algorithm and reduce the detection computational complexity.
