CORRELATION CODE TRANSMISSION SYSTEM

摘要

This invention relates to a correlation transmission coder or a correlation code transmission system that utilizes the correlation transmission coder. This 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. The correlation code transmission system includes a provision of means that reset or preset in each frame period registers that are used commonly by a transmission system and a precoder that makes up the coder. The system also includes a provision of means that insert immediately before the frame synchronization pattern internal data that is added to the transmission data by the transmission system and the precoder.
