ABSTRACT:
A radio receiver in which the received signal is spread and subsequently despread in order to identify unwanted signals. One embodiment of the present invention is comprised of a frequency-hopping spreading synthesizer that operates in synchronization with a despreader synthesizer such that unwanted signals are effectively suppressed based upon different spreading characteristics of the desired and undesired signals. Use of a logic device, in one case a digital signal processor, in combination with a state-level monitor allows for the reconfiguring of the receiver such that a state containing a large interferer can be removed from further signal processing.
