Abstract
The method and apparatus for time-division multiplexing/demultiplexing of signals multiplexes input signals, and a predetermined frame synchronization pattern signal to thereby generate the first time-division multiplexed signals, then multiplexes each of the first time-division multiplexed signals to thereby generate the second time-division multiplexed signal. After receiving from a transmission line, the time-division multiplexed signal is demultiplexed to thereby generate a predetermined number of first time-division demultiplexed signals, then each of the first time-division demultiplexed signals is demultiplexed to generate the second time-division demultiplexed signals, and the orders of the second time-division demultiplexed signals are permuted until the same signal as a predetermined frame synchronization pattern signal is obtained from the second time-division demultiplexed signal corresponding to the predetermined frame synchronization pattern signal of the second time-division demultiplexed signals.
