PARALLEL TRANSMISSION SYSTEM

摘要

PURPOSE:To use transmission code for another purpose by applying transmission line coding of a block form (mBnB) and taking a sufficiently long block length so as to eliminate the deterioration of margin due to delay difference. CONSTITUTION:Data is converted into a transmission line code of a block form in matching with a transmission line 4 through a transmission line code converter 3 in the block timing impressed from an input terminal 1 and the timings of the block are arranged and the result is sent to the line 4. As the form of the code, the block form (mBnB) is adopted to compensate the delay difference in the parallel transmission based on the phase of the block. It is required to increase m/n to a degree for the band effective use and to prolong the block length to a degree to compensate the delay difference (m/n>=2/3). For example, >=3-bit is used. Even if the transmission speed is increased, no deterioration of margin is caused, the utilizing efficiency of band is excellent and the delay compensation is attained by a simple circuit.
