METHOD AND SYSTEM FOR SWITCHING ANTENNAS DURING TRANSMISSION TIME INTERVALS IN OFDMA SYSTEMS

摘要

A method and system switches antennas in an orthogonal frequency division multiplexed access (OFDMA) wireless communication system while transmitting symbols. Each symbol includes a cyclic prefix and a block of data signals. The symbols are transmitted during a first portion of a transmission time interval (TTI), from a first antenna. Then, the RF chain is switched to a second antenna to transmit the symbols, and in which the switching is performed substantially between transmitting two consecutive transmitted symbols.
