1. A receiver for receiving a spread spectrum signal and including means for generating a code for dispreading, comprising:

  • a first timer;

    a second timer; and

    intermittent receiving control means for controlling intermittent operation of said receiver, wherein said intermittent receiving control means, in response to said first timer, controls a suspension period of intermittent receiving operation of said receiver, in response to said second timer, resumes receiving operation of said receiver by calculating a phase of spreading code for a received signal and setting a state value of dispreading code generating means based on the calculated phase of spreading code, and resumes demodulation operation of said receiver so as to demodulate a spread signal, and wherein a continuation time of the demodulation operation of said receiver is adjusted based on the calculated phase of spreading code.
