Abstract
In this letter, we derive a recursive, additive metric for complexity- constrained maximum likelihood detection for multiuser CDMA using brea dth-first detection algorithms. The metric requires linear filtering o f the matched-filtered received signal vector. It is shown that a clas s of filters fulfilling certain requirements lead to identical perform ance.
