Because of limited frequency band of channel, spreadspectrum and MFSK modulations can not resolve that high speed transmission is in contradiction with limited frequency band.
The system realization for the transmission of multiplexed testing signals using spreadspectrum technology based on DSP is discussed. The circuit system is devised.
