Adaptive MAP multi-user detection for fading CDMA channels
Christophe Andrieu, Arnaud Doucet, A. Touzni · 2002
This paper presents an adaptive multiuser maximum a posteriori (MAP) decoder for synchronous code division multiple access (CDMA) signals on fading channels. The key idea is to interpret this problem as an optimal filtering problem. An efficient particle filtering method is then developed to solve this complex estimation problem. Simulation results demonstrate the efficiency of our method.
