ABSTRACT:
A wireless communication system that transmits data on multiple carriers simultaneously to provide frequency diversity includes an antenna array, which may provide for transmit diversity. Complex coding applied to the carriers and carrier frequency separation control time-domain characteristics of a superposition of the carriers. Each transmitter of a transmitter array may be provided with at least one carrier of the multicarrier signal. A periodic relative phase relationship applied to the carriers causes a periodic variation in the transmitter array's beam pattern. A periodic phase relationship between the carriers provides periodic scanning of the beam pattern transmitted by the antenna array. Embodiments of the invention may be employed with OFDM and frequency hopping.
