Per-User Automatic Gain Control for an Uplink CDMA Receiver
Jungwoo Lee · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2006
A per-user AGC technique is proposed to combat the signal level variation of an individual user in a DS-CDMA receiver. A simple signal model for a Rake receiver is derived, and the potential cause of the signal variation in the Rake receiver output is discussed. The adaptive scheme is also compared with a conventional fixed quantization scheme in simulations.
