    Abstract: 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 (r i ) of at least one known datum, a predetermined value (p i ) of the known datum and a channel estimate (h i ). 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.

    Abstract: 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.

    Abstract: A method, a system (100) and a receiver device (107) provide timing and frequency correction in a spatial division multiple access (SDMA) system. A timing and frequency correction (TFC) logic/utility (110) obtains a timing error estimate by using pilot symbols on a slot of six tiles. The TFC logic estimates (412, 418) the timing error based on pilot phase differences between unique pairs of tiles when the frequency separation of the tiles is less than a threshold value. When none of the unique pairs of tiles satisfies the threshold value, the TFC logic estimates (412, 414) timing error based on an exhaustive search for each candidate phase error value. The TFC logic performs (426) timing error correction via a timing error estimate based on pilots from the symbols received on each antenna. The TFC logic performs (428) inexplicit frequency error correction according to phase differences based on relative symbol indices.
