Abstract:
A time-division multiplexing transmission system for multiplexing and transmitting a plurality of channels of signals which include at least one frame structure signal having frame structure in a time-division manner, the time-division multiplexing transmission system comprising:a transmitter having inversion means for inverting at least some of synchronization patterns in said frame structure signal, and time-division multiplexing means for multiplexing and transmitting a plurality of channels of signals which include a signal having the inverted synchronization patterns in a time-division manner; and a receiver having demultiplexing means for demultiplexing the time-division multiplexed channels into individual channels, frame synchronization means for performing frame synchronization on the basis of the channel having the inverted synchronization patterns among the demultiplexed channels, and channel identification means for using the frame synchronized channel as a reference and recognizing the remaining channels.
