Optimum thresholds of controlled pre-equalization in TDD MC-CDMA systems
Dawei Liu, Youxi Tang, Shaoqian Li · 2005
The uplink performance of TDD MC-CDMA with controlled pre-equalization in Rayleigh fading environment is investigated. Theoretical BER expression of BPSK modulation is derived. Corresponding simulations are carried out and fit for the analytic expression results. According to the theoretical analysis, the optimum thresholds and factors of controlled pre-equalization in MC-CDMA systems can be calculated directly; the system design and performance evaluation would be supported subsequently.
