Abstract :
We investigate parameter tracking of spatial-temporal equalization for IS-136 TDMA cellular/PCS systems. We present three parameter tracking algorithms: the diagonal loading minimum mean-square-error algorithm, which uses the diagonal loading to improve tracking ability, the 2-stage tracking algorithm, which uses diagonal loading in combination with a reduced complexity architecture, and the simplified 2-stage tracking algorithm, which further reduces the complexity to one M×M and one 3×3 matrix inversion for weight calculation with M antennas
