ABSTRACT:
A signal processing system detects the transmission characteristics of a channel thereby to compensate the output waveform of the channel into the most-optimum state. The impulse response of the channel is detected by transmitting a code having a keen autocorrelation from the transmission end and by determining the correlation between the received signal of the code transmitted and the same code of the aforementioned code at a reception end.
