SYSTEM AND METHOD FOR GAIN WEIGHTED CODE COMBINING FOR TWO BINARY PHASE SHIFT KEYING CODES

摘要

A method and system for generating a composite binary phase shift keying (BPSK) code from two independent component BPSK codes that is representative of the two component BPSK codes. In one implementation the method involves gain weighting each of the first and second component BPSK codes by its respective code power ratio to form first and second gain weighted codes. The first and second gain weighted codes are processed in accordance with an algorithm to form a composite BPSK code. The composite BPSK code has a fifty to seventy-five percent probability of matching each one of the BPSK codes. A system for generating a composite BPSK code from two BPSK codes is also disclosed.
