sending and receiving apparatus and method using a differential cyclic delay diversity MIMO techniques

摘要

differential cyclic delay diversity MIMO techniques for transmitting and receiving apparatus and method using the start is . Transmission apparatus using a differential cyclic delay diversity MIMO scheme is the current position of the device is a micro -cell (micro cell) area or a macro cell (macro cell) area that the terminal position determination unit configured to determine , based on the location of the at least one terminal , cyclic delays (cyclic shift delay) cyclic delay value setting section that sets the value , in the set of one or more cyclic delay signal generation unit and the one or more delay signal to generate one or more delay signal according to a cyclic delay value prefix (cyclic prefix ) and a transmission unit for transmitting the one or more transmission signals added by the MS .
