Abstract :
The diversity reception techniques used in multicarrier frequency-diversity spread spectrum multiple access systems (MCFD/SSMA) are researched. Due to the system architecture of the MCFD/SSMA, a frequency domain diversity receiving scheme is available in addition to the theoretically optimal RAKE receiving scheme. The former suffers an insignificant degradation of performance compared with the latter, while considerably simplifying the receiver architecture. MCFD/SSMA is a spectrum spreading method combining OFDM and CDMA techniques
