Abstract
PURPOSE:To improve the transmission efficiency by changing the number of consecutive transfer blocks or the length of block based on the quality of a transmission medium changing timewise so as to reduce the retransmission of the blocks due to occurrence of error. CONSTITUTION:A transmission control parameter decision circuit 8 recognizes the quality of a transmission medium 5 by dividing the value of total retransmission block counter 7 by a value of a total transmission block number counter 6. An upper limit and a lower limit of the quality are given to the transmission control parameter circuit 8 and when the quality of the transmission medium 5 is deteriorated from the lower limit value of the quality, the content of the consecutive transfer block number designation register 4 is decremented by one. Moreover, the value of the block length designation register 3 can be changed and both values of the consecutive block number designation register 4 and the block length designation register 3 are can be changed. Thus, the block number encountering the error is reduced and the block number resent due to the occurrence of error is reduced to improve the transmission quality.
