Blind Adaptive Multi-User Detection Applied to a Power-Line Data Transmission System

چکیده
In this paper the CMOE detector proposed in 111 is modified to cope with a varying SNR of the signal of interest in a multi-user environment. The detector is applied to a DS-CDMA system, where several users transmit data simultaneously and asynchronously over a noisy, frequency selective power-line channel. A comparison is performed between the improved CMOE detector and a RAKE receiver for a non-ideal power control. Simulation results show that the modified detector outperforms the RAKE receiver in terms of biterror-rate and overall system capacity. This performance gain is achieved without additional knowledge of the multiple access interference structure.
