Abstract
A direct sequence spread spectrum receiver samples an incoming signal and stores the sample in memory. Power is then inhibited to the tuner of the receiver to minimize power consumption. The signal sample may be read from memory when necessary to process the signal without further signal acquisition. Power to other receiver sections may be selectively controlled to minimize power consumption.
Such a receiver is useful in global positioning satellite (GPS) signal processing where the receiver has a limited power supply.
Such a receiver is useful in global positioning satellite (GPS) signal processing where the receiver has a limited power supply.
