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

摘要

PURPOSE: A digital radio communication system is provided to jointly mitigate the deleterious effects of fading, time dispersion and interference using interference rejection and diversity combining. CONSTITUTION: The digital radio communication system transmits the signals representing symbol order and receives the signal from two separated antenna. The signals are provided for signal sample to be received in each antenna. Each antenna estimates the channel tap. The branch metric by using signal sample to be received and channel tap. In one particular embodiment, the system performs interference rejection and diversity combining by separating a received signal into its in phase and quadrature components
