The adaptive step-size (AS) code-constrained minimum output energy
(CMOE) receiver for nonstationary code-division multiple
access (CDMA) channels is proposed. The AS-CMOE algorithm
adaptively varies the step-size in order to minimise the CMOE criterion.
Admissibility of the proposed method is confirmed via the
reformulation of the CMOE criterion as an unconstrained optimisation.
The ability of the algorithm to track sudden changes of the
channel structure in multipath fading channels is assessed. Sensitivity
to the initial values of the step-size and the adaptation rate of
the algorithm is also investigated.
