Query: A Monte-Carlo Implementation of the SAGE Algorithm for Joint Soft
  Multiuser and Channel Parameter Estimation   An efficient, joint transmission delay and channel parameter estimation
algorithm is proposed for uplink asynchronous direct-sequence code-division
multiple access (DS-CDMA) systems based on the space-alternating generalized
expectation maximization (SAGE) framework. The marginal likelihood of the
unknown parameters, averaged over the data sequence, as well as the expectation
and maximization steps of the SAGE algorithm are derived analytically. To
implement the proposed algorithm, a Markov Chain Monte Carlo (MCMC) technique,
called Gibbs sampling, is employed to compute the {\em a posteriori}
probabilities of data symbols in a computationally efficient way. Computer
simulations show that the proposed algorithm has excellent estimation
performance. This so-called MCMC-SAGE receiver is guaranteed to converge in
likelihood.
