PCT No. PCT/JP90/01118 Sec. 371 Date Jan. 15, 1991 Sec. 102(e) Date Jan. 15, 1991 PCT Filed Aug. 31, 1990 PCT Pub. No. WO91/11064 PCT Pub. Date Jul. 25, 1991.A correlation transmission coder or a correlation code transmission system whereby the correlation transmission coder generates a transmission signal to be sent on a transmission line, the transmission signal being determined, as with a partial response class 4 signal, by using already-transmitted data strings and data being transmitted by adding a specified length of frame synchronization pattern in each constant frame period. What is characteristic of this invention is the provision of which reset or preset in each frame period registers that are used commonly by a transmission system and a precoder that makes up the coder. Another characteristic is the provision of which inserts, immediately before the frame synchronization pattern, internal data that is added to the transmission data by the transmission system and the precoder.
