Abstract :
We address the problem of multiuser CDMA detection under fading conditions. The optimal detection problem can be reformulated as an optimal filtering problem for jump Markov linear systems, i.e., linear Gaussian state space models switching according to an unobserved finite state space Markov chain. Several approaches based on particle filtering techniques are reviewed to perform optimal filtering in this framework. A brief simulation study is carried out
