Bandwidth efficient OFDM transmitter diversity techniques

Abstract

Space-time coded orthogonal frequency division multiplexing (OFDM) transmitter diversity techniques have been shown to provide efficient means of achieving near optimal diversity gain in frequency-selective fading channels. However, these known techniques all require a cyclic prefix to be added to the transmitted symbols, resulting in significant bandwidth… (More)
