Abstract

A scheme consisting of a combination of orthogonal transmit diversity (OTD) and OFDM with power allocation is presented. The proposed scheme is a new approach to space-time-frequency coded OFDM (COFDM) that combines OFDM with orthogonal transmit diversity, power control and turbo codes so that the diversity in frequency, time and space is exploited to provide high quality of transmission for wireless communications over frequency selective fading channels with enhanced performance in terms of spectral and power efficiency.
