Abstract :
We present an adaptive interference canceler in multiuser and multipath scenarios. The detector has two key elements: an adaptive algorithm for separating the signal subspace from the noise subspace and a decision feedback equalizer based on the generalized cerebellar model articulation controller (GCMAC) neural network. Examples demonstrate the performance of this equalizer in typical mobile channels
