ABSTRACT:
A signal detector includes a transform unit and a signal alignment unit. The transform unit is adapted to receive a plurality of frames of time domain input samples and generate a plurality of energy values based on the frames of time domain input samples. Each energy value is associated with one of the plurality of frames. The signal alignment unit is adapted to identify at least a first partial energy frame and a second partial energy frame from the plurality of frames. The first partial energy frame is associated with a first frequency and has a first energy value. The second partial energy frame is associated with a second frequency and has a second energy value. The signal alignment unit determines a misalignment between the first and second partial energy frames based on the first and second energy values. A method for detecting a signal is provided. The method includes generating a plurality of energy values based on the frames of time domain input samples. Each energy value is associated with one of the plurality of frames. At least a first partial energy frame and a second partial energy frame are identified from the plurality of frames. The first partial energy frame is associated with a first frequency and has a first energy value. The second partial energy frame is associated with a second frequency and has a second energy value. A misalignment between the first and second partial energy frames is determined based on the first and second energy values.
