The radio communication apparatus (10) comprises a buffer (14) which temporarily stores data to be sent, a transmission/receiving circuit (12) having a data transmission circuit (30) and a data receiving circuit (40). The data transmission circuit (30) includes an input processor (41) which generates, when transmitting the data, a preamble to output it to a QPSK modulator (42), thereafter reads from the buffer (14) a data row of 256 bits and outputs it to the QPSK modulator (42). Accordingly, the transmission circuit (30) 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 (40) includes a DMF (86) which accomplishes acquisition using a portion in the received data corresponding to the preamble.
