SPEED-SPECTRUM DEMODULATION SYSTEM FOR SUPPRESSION OF INTERFERING SIGNALS

摘要

A spread-spectrum demodulation system which can separate known incoming broad-band signals from a received signal, allowing separation of interfering signals and acquisition and tracking of multiple signals with widely varying power. Each signal is despread using a locally generated code, and then separated by narrow-band excision. The effect of that locally generated code on each of the remaining signals is eliminated by mixing again with a locally generated code.
