Abstract

PURPOSE:To reduce crosstalk when number of transmitters is increased by adopting the system dividing a data string into plural channels and sending it repetitively, increasing number of repetitive transmission sequentially from the 1st channel and increasing sequentially the transmission period by an optional integral number of multiple each thereby sending surely the data for each channel. CONSTITUTION:A data string obtained by modulating a high frequency signal by a low frequency signal is divided into plural channels and sent repetitively. The number of repetitive transmission of the n-th channel data is defined as 2<n>-1 and the transmission period as nXT, where (n) is a positive integer and T is the transmission period of the 1st stage of channel data. Then the number of repetitive transmission 2<n>-1 is increased sequentially from the 1st channel for each data string and the transmission period nXT is increased sequentially by an optional number of multiple each thereby receiving surely the data of each channel.
