Waiting circuit |
摘要 |
A waiting circuit which is utilized in a mobile communication system. The waiting circuit detects a predetermined signal from a base station. The waiting circuit starts other circuits in the mobile communication system which are in a sleep mode when the predetermined signal is received. The predetermined signal is generated in the base station. The predetermined signal has a speed equal to a predetermined symbol rate and is modulated to be an intermediate frequency signal. The intermediate frequency signal is sampled in response to a sampling clock that has a speed equal to an integer times the symbol rate. The sampled intermediate frequency signal is input to a match filter which multiplies the sample signal by a predetermined sequence of coefficients.
