Abstract
The radio communication apparatus ( ) comprises a buffer ( ) which temporarily stores data to be sent, a transmission/receiving circuit ( ) having a data transmission circuit ( ) and a data receiving circuit ( ). The data transmission circuit ( ) includes an input processor ( ) which generates, when transmitting the data, a preamble to output it to a QPSK modulator ( ), thereafter reads from the buffer ( ) a data row of 256 bits and outputs it to the QPSK modulator ( ). Accordingly, the transmission circuit ( ) is constituted such that the data sets each including the preamble and the data row are repeatedly transmitted. On the other hand, the receiving circuit ( ) includes a DMF ( ) which accomplishes acquisition using a portion in the received data corresponding to the preamble.
