Claim:
1. A communication device, comprising: a symbol encoder configured to encode information bits into frequency domain data corresponding to multicarrier frequency domain symbols (MFDSs); an encoder configured to generate modified frequency domain data when the communication device is operating in a diversity transmission mode, the modified frequency domain data comprising re-ordered complex conjugate data corresponding to the frequency domain data; a converter configured to i) convert the frequency domain data to a first time domain signal, and ii) convert the modified frequency domain data to a second time domain signal when the communication device is operating in the diversity transmission mode; a first radio frequency (RF) transmitter configured to transmit the first time domain signal; a second RF transmitter configured to i) transmit the second time domain signal when the communication device is operating in the diversity transmission mode, and ii) not transmit the second time domain signal when the communication device is operating in a legacy mode; and logic circuitry configured to control operation of the communication device according to one of a plurality of transmission modes comprising the diversity transmission mode and the legacy mode.
