Abstract
A mobile telephone system includes a base station which establishes a link with a selected mobile station. The received signal from the mobile station will include a noise component as well as a possible interference component from another mobile station operating at the same frequency in another cell. The base station has a trellis based equalization system which operates on the assumption that the received signal includes components which have a predominantly Gaussian characteristic. A switch controller determines when the interference component (which is non-gaussian) in the received signal becomes a dominant component and operates to switch a spatio-temporal filter into the circuit instead of the trellis based equalization system, to improve the bit error rate performance.
