<p>PURPOSE: To improve efficiency in using of a certain frequency band width and to increase a channel capacity by detecting a desired signal by a signal reduced in multi-spot connection disturbance. CONSTITUTION: A delayed signal is subtracted from a signal output added in an adding circuit 725 by a difference circuit 727. Thus, obtained difference signal is divided into several branches equivalent to the number of 'U' channels, added to pseudo receiving circuits 731 to 733 to be restored into an original information signal showing an uncertain signal 'U'. These 'U' signal outputs of the pseudo receiving circuits 731 to 733 are supplied to a storage circuit 712 in order to overwrite there the stored signals 'U' which are perhaps originally wrong. These 'U' signals become more correct, and then they are supplied to a pseudo receiver 741 for error correction and decoding or the like.</p> |
