A severe frequency-selective fading, encountered in a broadband wireless mobile communication, significantly degrades the single-carrier (SC) signal transmission performance. In this paper, multi-antenna frequency-domain pre-equalization (called pre-FDE) is presented for spread-spectrum single-carrier (SC) systems. At a transmitter, pre-FDE with transmit power constraint is applied for each transmit antenna; no equalization function is necessary at a receiver. It is shown by computer simulation that pre-FDE transmission can provide significant improvement in the bit error rate (BER) performance in a frequency-selective Rayleigh fading channel and can achieve a BER performance close to that attainable by FDE reception. For a mobile communication system, the pre-FDE transmission for the downlink (base-to-mobile) and FDE reception for the uplink (mobile-to-base) can be implemented at a base station. This allows a simple implementation of mobile transceivers.
