Abstract
A signal receiving system for spread spectrum communication including receiving a signal produced by multiplying a data to be transmitted by a predetermined spread code sequence through spread spectrum modulation and performing spread spectrum demodulation by multiplying the received signal by an attenuation spread code sequence prepared by predetermined attenuation or amplification to each chip of the spread code sequence used on that modulation.
