Frequency-Domain Pre-Equalization Transmit Diversity for MC-CDMA Uplink Transmission
Recently, multi-carrier code division multiple access (MC-CDMA) has been attracting much attention for the broadband wireless access in the next generation mobile communications systems. In the case of uplink transmissions, the orthogonality among users’ signals is lost since each user’s signal goes through different fading channel and hence, multi-access interference (MAI) is produced, thereby...

متن کاملFrequency Domain Transmit Equalization for Uplink MC-CDMA
Abstract In multi carrier code division multiple access (MC-CDMA), since signals transmitted from different users go through different frequency-selective fading channels, the use of frequency-domain equalization at a receiver can only partially restore the orthogonality property among different users’ signals, resulting in the degraded bit error ratio (BER) performance due to large multi-acces...
متن کاملThe Uplink BER Performance of MC-CDMA with Frequency-domain Pre-equalization Transmit Diversity
Abstract Recently, multi-carrier code division multiple access (MC-CDMA) has been attracting much attention for the broadband wireless access in the next generation mobile communications systems. In the case of uplink transmissions, the orthogonality among users’ signals is destroyed since each user’s signal goes through different fading channel and hence, the use of frequency-domain pre-equali...
متن کاملFrequency-Domain Pre-Equalization for MC-CDMA/TDD Uplink and Its Bit Error Rate Analysis
In multi-carrier code division multiple access (MCCDMA) uplink (mobile-to-base station), since different users’ signals go through different frequency-selective fading channels, large multi-access interference (MAI) is produced. The use of frequency-domain equalization reception can only partially restore the orthogonality among different users’ signals, resulting in a severe degradation in the...
