摘要： An apparatus (100) and method dynamically allocates radio frequency receive path resources as required by a programmable location engine (112). The programmable location engine (112) employs cascaded time of arrival and direction of arrival algorithms to determine per remote unit location data. The apparatus (100) employs a phased array antenna (104) and a programmable receiver switching apparatus (108). A plurality of radio frequency receivers (102a-102n) receive a plurality of different carriers, such as CDMA carriers, on each of a different phased array antenna element (106a-106d). An RF switching matrix (126) and mobile location shared resource controller (110) dynamically switch the plurality of radio frequency receivers (102a-102b) to not only receive the different carriers on each of the different phased antenna radio elements to determine time of arrival information, but alternately receive a same carrier signal over all or a portion of the phased array antenna elements to determine direction of arrival information.

摘要： A digital receiver (200) and a transmitter (300), wherein the digital receiver includes a plurality of antennas (202) for receiving uplink radio frequency signals; a plurality of analog to digital converters (210) for converting the received radio frequency signals into digital signals; a switched digital down converter (214) for down converting one of the digital signals to a baseband IF signal; and a channel processor (228) for recovering one of a plurality of communication channels contained within the baseband IF signal.

摘要： A method for selecting at least one operating parameter of a communication system (100). The method can include determining a receive signal strength indicator (RSSI) for a communication signal (330). An intermediate value (D) for the communication signal can be determined based on, at least in part, a received value (ri) of at least one known datum, a predetermined value (pi) of the known datum and a channel estimate (hi ). Further, a carrier to interference and noise ratio (CINR) can be estimated based on, at least in part, the RSSI and the intermediate value. The operating parameter can be selected based on, at least in part, the estimated CINR.

摘要： An apparatus and a method for routing digitized radio frequency (RF) signals (140-143) to a plurality of paths are described herein. In accordance with a first preferred embodiment, the apparatus includes a digital converter/modulator (DUC) (125 or 129) coupled to a scaling and switching network (100N) which includes, at least, a first, second, third and fourth digital switch, and a first, second and third adder. Within the scaling and switching network, the first digital switch is responsive to the DUC. The first adder is responsive to the first and second digital switches, while the second adder is responsive to the third and fourth digital switches. Finally, the third adder is responsive to the first and second adders.
