Abstract
A communication apparatus includes a signal detector that detects incoming (i.e., receives) information from a signal received wirelessly. The signal detector includes a wave detector, an equalizer, and a detector. The wave detector accepts an incoming signal wherein information is modulated onto a carrier signal, analyzes the envelope variation of the incoming signal, and generates a detection signal containing the incoming information. The equalizer corrects the detection signal and outputs a corrected detection signal. The detector then detects the incoming information from the corrected detection signal.
