Abstract

A method of detecting signals transmitted using differential cyclic delay diversity is provided, the method includes the steps of computing a plurality of fading coefficient matrices (101), wherein the fading coefficient matrices (101) are generated using received sequences of Nm observation symbols; determining possible transmitted symbol based on communication data (102), wherein the communication data (102) is a set Sv(n) of possible information symbols; computing transmitted symbol based on an algorithm (103), wherein the transmitted symbol is able to be computed by solving an optimisation problem; and determining maximum value of estimated symbol sequence (104), wherein the maximum value is maximum likelihood detection that is specifying used in finding the transmitted symbol; wherein the transmitted symbols are based on communication data such as M-ary communication data and the method is a Multiple Symbol Differential Detection (MSDD) for wireless communication.
