    摘要: A digital communication system using superposed transmission of high and low speed digital signals capable of transmitting superposed high and low speed digital signals through an identical frequency band efficiently by increasing a simultaneously transmittable number of channels in the low speed digital signals, while achieving the practically reasonable bit error rate performances for both the high speed digital signals and the low speed digital signals. In this system, the low speed digital signals are transmitted in a form of spread spectrum signals and the high speed digital signals are cancelled out from the superposed transmission signals in obtaining the output low speed digital signals by using the phase inverted replica of the high speed digital signals to be combined with the superposed transmission signals, so that it becomes possible to increase a number of channels for the low speed digital signals, while achieving the practically reasonable bit error rate performances for both the high speed digital signals and the low speed digital signals.
