Abstract: A method and apparatus for providing a base station with a timing reference that is precise and cost effective using assisting information to facilitate detection of, and extraction of system timing information from, satellite signals by the base station, thereby decreasing the intervals during which system timing information is unavailable and eliminating the need for a highly stabilized oscillator at the base station. Assisting information is any information which may be used by the base station to facilitate detection of satellite signals. Assisting information may include identities of satellites and satellite signal estimates, such as predicted navigation data, a Doppler frequency estimate, a code phase estimate, Doppler frequency and code phase search windows, etc. The satellite signal estimates are based on the known or current location of the base station.

Abstract: A technique for receiving and transmitting wireless telecommunications through use of a generic architecture is disclosed. The present invention mitigates the complexity of different transceiver operations by allowing a generic architecture to be used in a variety of situations with different channels and different telecommunications standards. An illustrative embodiment of the present invention comprises: receiving uplink analog RF signals at a base station; converting the uplink analog wide-band RF signals into IF uplink digital signals at an analog-to-digital converter; converting the IF uplink digital signals into a number of uplink channels; and demodulating selected narrow-band uplink channels from the total number of narrow-band uplink channels.

Abstract: A block radio design is disclosed that prevents the primary analog-to-digital converter from saturating and thus prevents the introduction of intermodulation products into the multi-carrier signal. The block radio comprises a strong signal suppressor that selectively suppresses any carrier signal in the multi-carrier signal before the multi-carrier signal is digitized by the analog-to-digital converter, thus preventing the possibility that the analog-to-digital converter can be saturated. Furthermore, the strong signal suppressor attenuates the stronger carrier signals without affecting the weaker carrier signals.
