Abstract
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.

A method for switching antennas in an orthogonal frequency division multiplexed access (OFDMA) wireless communication system while transmitting symbols, each symbol including a cyclic prefix and a block of data signals, comprising:
- transmitting the symbols during a first portion of a transmission time interval (TTI), from a first antenna connected to an RF chain;
- and
- switching, during a second portion of the TTI, the RF chain to a second antenna to transmit the symbols, in which the switching is performed substantially between transmitting two consecutive symbols.
