Abstract
A Baseband receiver including a CIR estimate block, gain, phase and timing loops, a CMF, a single-carrier processor and a multi-carrier processor. The CIR estimate block generates 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. The single-carrier segment has a spectrum that approximates a multi-carrier spectrum. The gain, phase and timing loops adjust gain, phase, frequency and timing to provide an adjusted receive signal. The CMF filters the adjusted receive signal according to the impulse response signal. The single-carrier processor processes the adjusted and filtered receive signal to resolve a single-carrier segment of a mixed carrier signal. The single-carrier processor detects a mixed carrier mode indication in a single-carrier segment and asserts a start indication. The multi-carrier processor processes a multi-carrier segment of a mixed carrier signal in response to assertion of the start indication.
