WIRELESS COMMUNICATION SYSTEM FOR REDUCING POWER CONSUMPTION WHEN RECEIVING A FRAME HAVING A LOW RECEPTION SUCCESS POSSIBILITY

摘要

A header analysis unit reads a parameter showing a format of a digital signal contained in a received signal. A received signal quality measurement unit measures a quality of the received signal. An awake/sleep control unit controls restart and sleep of a reception unit based on data from the header analysis unit and the received signal quality measurement unit. The awake/sleep control unit stops a reception operation for a period corresponding to a frame length when the quality of the leading portion of the received signal is less than a predetermined threshold.
