Patent ID: RE43670

Claim:
A baseband receiver, comprising: a channel impulse response (CIR) estimate block that is capable of generating an impulse response signal based on a receive signal that is a single-carrier signal or a single-carrier segment of a mixed carrier signal in which the single-carrier segment has a spectrum that approximates a multi-carrier spectrum; gain, phase and timing loops that adjust gain, phase, frequency and timing of the receive signal to provide an adjusted receive signal; a channel matched filter (CMF), coupled to the CIR estimate block, that filters the adjusted receive signal according to the impulse response signal; a single-carrier processor that processes the adjusted and filtered receive signal to resolve the single-carrier segment of the mixed carrier signal, the single-carrier processor capable of detecting a mixed carrier mode indication in the single-carrier segment and asserting a start indication corresponding to the end of the single-carrier segment; and a multi-carrier processor capable of processing a multi-carrier segment of the mixed carrier signal in response to assertion of the start indication.
