Abstract
A method and apparatus for a multicarrier receiver circuit with guard interval size detection is described. The invention allows the FFT size and guard interval size to be detected quickly, even in the presence of relatively noisy input signals. The method is robust in noisy environments, and also sufficiently robust to process signals having severe multipath and/or co-channel interference. Moreover, the method is of low complexity, and can be implemented in a VLSI circuit.
