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.

Disclosed is a method for efficiently transmitting and receiving control information messages necessary for a Multimedia Broadcast/Multicast Service (MBMS) provided in a mobile communication system. The method includes setting information elements for the control information messages to reduce unnecessary signaling overhead during the transmission of the control information. The method prevents a user equipment (UE) from performing duplicate reception on the control information, thereby reducing power consumption of a battery.

A direct sequence spread spectrum receiver samples an incoming signal and stores the sample in memory. Prior to sampling and storage, the incoming signal is translated to an IF signal. Also prior to storage, the IF signal is corrected for a frequency offset signal. The frequency offset may be caused by many sources, Doppler shift or local oscillator error, for example. Once the signal is corrected for the frequency offset, the signal sample is stored in memory. The signal sample is read from memory as necessary to process the signal. Such a receiver is useful in global positioning satellite (GPS) signal processing where the incoming signal contains several satellite transmissions encoded with CDMA encoding.

A direct sequence spread spectrum receiver samples an incoming signal and translates the signal to an IF signal. The IF signal is sampled and stored in memory. In one embodiment, the memory consists of two memory banks which alternately receive sample segments. During a write period to one of the memory banks, the other memory bank supplies its output to a processor. This continues in a ping-pong manner. In another embodiment, a single memory bank is filled and read as necessary, the receiver ignoring incoming signal until the processor has completed processing the sample available at the output of the memory. Such a receiver is useful in global positioning satellite (GPS) signal processing where the incoming signal contains several satellite transmissions encoded with CDMA encoding.

A method of providing an authenticable time-and-location indication using a radio-navigation signal receiver comprises receiving radio-navigation signals broadcast from a plurality of radio-navigation signal sources, at least some of the radio-navigation signals containing one or more cryptographic tokens protected by encryption, the cryptographic tokens being updated from time to time. The receiver retrieves, by decryption, the cryptographic tokens from the radio-navigation signals containing them. The receiver then determines positioning data, representing its geographical position and time, based on the radio-navigation signals received. The receiver generates a digital authentication code using a cryptographic function taking as inputs at least the positioning data and the retrieved cryptographic tokens, and produces a data package including a first part containing the positioning data and a second part containing the digital authentication code.

A direct sequence spread spectrum architecture permits low power consumption during a synchronization phase of data reception by allowing the receiver to be turned off during most of the acquisition phase of reception, or by using a parallel correlator to keep acquisition time short. The architecture is particularly suitable for global positioning satellite (GPS) signal processing and permits multiple satellite codes and multiple Doppler bins to be searched either sequentially, without requiring the receiver to be turned on during the search process. The receiver output baseband data is sampled and stored over a time interval sufficient to achieve acquisition and synchronization for any one code division multiple access (CDMA) signal at any specific Doppler shift. This sample is digitally recorded and re-played from memory as many times as may be required to acquire and synchronize each desired CDMA signal. To keep processing energy consumption low, an analog (capacitor-based) cross-correlator is used. The order of coherent and non-coherent processing for all code-Doppler channels is chosen to maximize energy efficiency while minimizing required processor hardware.

If an encrypted pattern is included in the address, the server performs processing according to the command obtained by decrypting the pattern.
