SIGNAL ACQUISITION SYSTEM FOR SPREAD SPECTRUM RECEIVER |
摘要 |
The invention relates to a device detecting a demodulated signal received by a spread spectrum receiver and converted into digital samples. The device is characterized by comprising a matched filter (4-16) for calculating the correlation between an incoming signal and at least one reference signal; an oscillator (4-8) for generating a sampling frequency; a sampling circuit (4-10) for re-sampling said demodulated digital sample signal at said sampling frequency, which is such that the timing of samples of the reference signals of the matched filter (4-16) corresponds to the timing of a sample signal going from the sampling circuit to the matched filter (4-16); and a multiplier (4-12) in which the sample signal is multiplied by a carrier replica generated locally before the sampling circuit or thereafter, to remove the carrier from the sample signal.
