Abstract
A system and method for reducing ICI in multicarrier systems is disclosed. The system uses a primary transmission path to transmit a first signal using the same techniques as conventional OFDM and a second transmission path to transmit a conjugate of the first signal. The differing transmission paths can be implemented on separate channels via a variety of multiplexing and/or diversity techniques.
