Abstract
Various embodiments of wireless communication systems and methods in which the system seamlessly dual-uses a receiver chain for incoming transmissions and for other signal sensing purposes. The system is configured such that there are multiple receiver chains, and at least one receiver chain alternates between receiving a communication signal with information payload and receiving other signals solely for the purposes of monitoring and/or improving some aspects of the system. In various embodiments, the alternating receiver chain receives alternatively signals with information payloads and signals which have passes through a power amplifier with amplifier distortion characteristics. In various embodiments, the alternating receiver chain receives alternatively signals with information payloads and signals which may be associated with background noise, or other radio transmissions.

25. A wireless communication system comprising:
-
a receiver coupled to a receiver interface, said receiver interface receiving a first signal from a first receiver chain and a second signal from a second receiver chain, said first receiver chain coupled to a first antenna, said second receiver chain coupled to a second antenna, said first antenna and said second antenna receiving a wireless transmission, said receiver interface operative to route said first signal and said second signal to said receiver; said receiver interface also operative to utilize said second receiver chain for reception of a third signal not associated with said incoming wireless transmission during a period, said second signal becoming unavailable to said receiver interface during said period; and said receiver interface operative, during said period, to substitute to said receiver said second signal with a duplication of said first signal. - View Dependent Claims (26, 27, 28)

29. A wireless communication system comprising:
-
a clipping mechanism configured to a first clipping level; a filter, an input of said filter coupled to an output of said clipping mechanism; wherein, a modulated signal is input to said clipping mechanism to form a clipped signal at said first clipping level, said clipped signal out-of-band filtered by said filter to produce a clipped and filtered signal. - View Dependent Claims (30, 31)
