Patent ID: 8817851

Claim:
A wireless communication device which modulates data of a communication frame into a signal, transmits the signal by wireless and demodulates a received signal received by wireless into a received communication frame, comprising: a transmission frame generator unit which generates a communication frame for transmission by allocating header information including a physical address-information to a header portion of the communication frame, and also allocating a plurality of redundant pieces of the header information and data error checking codes for detecting respective errors of the plurality of the redundant pieces of the header information to a data portion of the communication frame; a redundancy selector/generator unit which checks presence/absence of the respective errors in the plurality of the redundant pieces of the header information from the received communication frame based on the data error checking codes, and selects one from the plurality of the redundant pieces of the header information contained in the received communication frame or generates a predetermined physical address from the redundant pieces of the header information based on the checking; and a determination unit which determines whether the received communication frame is addressed to the wireless communication device or not, based on the physical address information selected or generated by the redundancy selector/generator unit, wherein a majority determination processing is performed when determination is made that all the redundant pieces of the header information in the checking are in error.
