Abstract:
1. A signal processing system comprising: a detection circuit comprising: a first signal processing portion adapted to receive a plurality of first signals from at least one signal receiver system and output a plurality of second signals based upon power levels of each of said plurality of first signals, wherein said plurality of second signals comprise active signals and null signals where said active signals are relatively higher than said null signals by a first predetermined value; a second signal processing portion adapted to output a first data determined based upon nulls per unit time; a third signal processing portion adapted to output a second data determined based upon said active signals; a fourth signal processing portion adapted to compare said first data with a second predetermined value and output a third data if said first data exceeds said second predetermined value; and a fifth signal processing portion adapted to compare said second data with a third predetermined value and output a fourth data if said second data exceeds said third predetermined value.
