ABSTRACT:
A transmission control section101temporarily stores a transmission signal, outputs the stored transmission signal to a coding section102and outputs transmission timing information to a counter section107. A preamble insertion section104inserts AGC preambles corresponding to the number set by a preamble number control section110into the transmission signal. The preamble number control section110compares a transmission time interval input from a subtraction section109with a threshold, decides to insert ten AGC preambles into the transmission signal when the transmission time interval is equal to or greater than the threshold and decides to insert five AGC preambles into the transmission signal when the transmission time interval is smaller than the threshold. By so doing, it is possible to make the transmission efficiency compatible with the error rate characteristic.
