Abstract
When a wireless communication apparatus transmits a data frame requesting an ACK frame, it is expected that a receiver station will transmit the ACK frame. A preamble analyzer analyzes whether or not a preamble pattern added to the header of a received frame exists from the time it is expected that the ACK frame will be received. When a desired preamble pattern is detected, the preamble analyzer supplies instructions to start an operation of demodulating a reception signal to a demodulator via a controller.
