Communication apparatus, communication frame format, and signal processing method

摘要

A communication apparatus includes a signal detection section that detects received information from a signal received through wireless communication. The signal detection section includes: a wave detection section that receives a signal in which the received information is superimposed on a carrier signal and that analyzes variations in an envelope of the received signal to generate a wave-detection signal containing the received information; an equalization processing section that corrects the wave-detection signal to output a corrected wave-detection signal; a detection section that receives the corrected wave-detection signal to detect the received information; and a training data detection section that detects from the received signal a training-data-detection sync signal allowing detection of training data utilized to optimize equalization characteristics of the equalization processing section. The equalization processing section starts a training process, in which the training data contained in the received signal are utilized, on the basis of the sync signal.
