METHOD AND APPARATUS FOR INTERFERENCE REJECTION WITH DIFFERENT BEAMS, POLARIZATIONS, AND PHASE REFERENCES

摘要

A digital radio communication system includes processing to jointly mitigate the deleterious effects of fading, time dispersion and interference using interference rejection and diversity combining. The system employs a selection processor for preliminarily reducing the number of signals for interference rejection and diversity combining based on one or more criterion. The system accommodates signals from dual polarized antennas. In one particular embodiment, the system performs interference rejection and diversity combining by separating a received signal into its in-phase and quadrature components.
