Abstract
Peak power reduction in space-time coded orthogonal frequency division multiplexing systems (OFDM) is a challenging task. Most of the current peak power reduction schemes reduce the peak power by manipulating the signal at the final IDFT process. However, in the case of space-time coded OFDM, any processing at this stage would violate the space-time code structure making it impossible to detect at the receiver. This paper shows that selected mapping (SLM) reduces the peak power of space-time coded OFDM signals without violating the space-time code. Reduced peak power of the OFDM signal relaxes the strict dynamic range requirements of the transmitter.
