Abstract
A parallel pulse transmission system, wherein the sending side converts original signals into line coded signals of a block coding type (mBnB line codes, m/2.gtoreq.2/3, n.gtoreq.3) and transmits them after aligning the timings of the blocks receiving side. The regenerates of the systems transmitted line codes and thereafter, aligns the timings of blocks of the line codes.
Claims9
A parallel transmission system comprising:
- a plurality of line coders for converting parallel original signals into parallel mBnB line codes, each code including a series of n-bit blocks, and each block including an m-bit word, where m and n are natural numbers;
- a block timing clock signal for aligning phases of the blocks of said mBnB line codes;
- a plurality of parallel transmission lines for transmitting said parallel mBnB line codes from said line codes wherein each transmission line transmits an mBnB line code;
- a plurality of receiver circuits for receiving said parallel mBnB line codes from said line coders;
- and
- delay difference compensation means for aligning the phases of the blocks of the parallel mBnB line codes received by said receiver circuits based on a reference signal.
A parallel transmission system comprising:
- means for converting parallel original signals into parallel mBnB line codes each code including a series of n-bit blocks, each block including an m-bit word and the phases of the blocks of said mBnB line codes being aligned;
- means connected to said converting means for receiving said parallel mBnB line codes through parallel transmission lines;
- and
- means for aligning the phases of the blocks of said received parallel mBnB line codes based on a reference signal.
A parallel transmission method comprising the steps of:
- converting parallel original signals into parallel mBnB line codes each code including a series of n-bit blocks, and each block including an m-bit word;
- aligning the phases of the blocks of said parallel mBnB line codes;
- transmitting said mBnB line codes with the phases having been aligned with one another;
- receiving each mBnB line code after the transmitting step;
- and
- aligning the phases of the blocks of the received parallel mBnB line codes based on a reference signal.
