Abstract
In a word synchronous system for a word interleave method in a digital communication system, the word synchronous system includes a line demultiplexing unit that receives a higher order signal for demultiplexing lower order signals therefrom; a window generating unit operatively connected to the line demultiplexing unit for generating windows to demultiplex the lower order signals from the higher order signal in the line demultiplexing unit; and a plurality of sub-demultiplexing units operatively connected to the line demultiplexing unit for receiving corresponding lower order signals from the line demultiplexing unit; wherein the window generating unit receives any one of lower order signals from the line demultiplexing unit and performs the detection of frame synchronous words from said lower order signal, when the window generating unit detects any one of frame synchronous words, the window generating unit performs a bit shift operation for the window in such a way that the bits are immediately shifted to the frame synchronous word to obtain synchronization with the window.
