Abstract

Based on a new formulation derived from array signal processing theory, we develop in this contribution the subspace-tracking array-receiver (STAR) for cellular CDMA in a multipath environment. The new receiver, STAR, shows fast tracking capability in the presence of strong nonstationarities, requires a low order of computational complexity and increases the uplink capacity of the CDMA system in terms of number of users per cell.
