Impact of Channel Estimation Errors on Multiuser Detection via the Replica Method

EURASIP Journal on Wireless Communications and Networking volume 2005, Article number: 807350 (2005) Cite this article

Abstract

For practical wireless DS-CDMA systems, channel estimation is imperfect due to noise and interference. In this paper, the impact of channel estimation errors on multiuser detection (MUD) is analyzed under the framework of the replica method. System performance is obtained in the large system limit for optimal MUD, linear MUD, and turbo MUD, and is validated by numerical results for finite systems.
