Abstract:
1. A diversity transmitter, comprising: a symbol encoder configured to encode data in a multicarrier frequency domain symbol (MFDS); a space frequency encoder responsive to said symbol encoder and configured to modify the MFDS in a first operational mode, the modified MFDS comprising a re-ordered subcarrier complex conjugate of the MFDS; a conversion unit responsive to said space frequency encoder and configured to convert the MFDS and the modified MFDS into first time domain counterparts respectively in the first operational mode and convert the MFDS into a second time domain counterpart corresponding thereto in a second operational mode; an RF transmission unit responsive to the conversion unit and configured to transmit the first time domain counterparts in the first operational mode and transmit the second time domain counterpart in the second operational mode; and a control logic configured to control operation of the diversity transmitter to one of the first and second operational modes, wherein the first operational mode is a diversity transmission mode and the second operational mode is a legacy transmission mode.
