RECEIVER WITH ORTHOGONAL BEAM FORMING TECHNIQUE

摘要

A receiver with orthogonal beam forming technique is achieved that is capable of differentiating different signal components within the received composite signal. An adaptive processor is used to eliminate the signal component whose phase information is known or can be calculated. The phase information of the major component of a signal can be easily acquired by using a limiter. The phase information of other signal components can be acquired by their direction information and other characteristics, such as modulation scheme, etc. Multiple orthogonal beams can be formed by eliminating one unwanted signal component each time by the adaptive processor until all unwanted signal is eliminated. Thus, a composite signal from multiple sources can be broken down into their component signals.

1. A signal processing unit comprising:
a first limiter configured to approximate a first value of a sample of a first signal into a second value; a first weighting processor configured to apply a first complex weight to said first signal so as to generate a second signal; and a first adaptive processor configured to update said first complex weight based on first information associated with said second signal and said second value.
