Detection and processing of spread spectrum signals

Abstract

A wireless communication device includes a processor that determines a signal type is one of a spread spectrum signal or a non-spread spectrum signal. The determination is based on a signal-type analysis on digitized down-converted signals. The digitized down-converted signals are input signals in a plurality of different intermediate frequency bands. The processor executes a multi-dimensional signal state processing operation to generate a plurality of signal state representations for each intermediate frequency band of a plurality of different intermediate frequency bands when the determined signal type is the spread spectrum signal. The processor determines one or more correlated signal patterns across the generated plurality of signal state representations when the determined signal type is the spread spectrum signal. The processor controls the wireless communication device to trigger an operational response based on the determined one or more correlated signal patterns.
