Decorrelation MUD for MC-CDMA in an Uplink Transmission Mode
This work focuses on the analysis of the decorrelation process of a MC-CDMA system in an asynchronous multi-user detection, reducing both the self interference due to the multipath, and the multi-user interference due to the effect of the uplink asynchronous reception mode at the base station. The analysis involves a comparative with the synchronous transmission mode and attemptes to reflect the bit error rate performance considering several users. The multi-user detection (MUD) is based on the knowledge of the channel impulse response of the different transmitted user’s signals.
