Abstract: A cellular telephone includes cellular telephone circuitry and an FM receiver. An FM signal being received is downconverted by a mixer. The downconverted signal is processed to generate an FM signal that is supplied to a digital IF filter. If a blocker emitted by the cellular telephone circuitry would interfere with receiving of the FM signal due to interaction of an LO harmonic with the blocker if a conventional LO frequency were used, then a different LO frequency is used. Subsequent processing of the downconverted FM signal (for example, by a digital complex conjugate selector and an IF rotator) results in the signal supplied to the digital IF filter having the same center frequency as the digital IF filter despite the use of the different LO frequency. In some embodiments, the LO is shifted by different amounts depending on cellular telephone mode and on the FM signal.

Abstract: A method of switching between Coherent and Non-Coherent demodulation based on computed metrics, in cases where stereo FM broadcasting stations do not adhere to RDS broadcast specifications. Re-utilizes existing hardware to demodulate RDS data in mono. The residual frequency offset is resolved using a Non Coherent demodulator and a time tracking algorithm. RDS data relies on the 57 kHz sub-carrier that is generated using 19 kHz pilot tone. In Mono broadcasting pilot tone is not present. A local 57 kHz free running signal is generated, and this is then used to demodulate the RDS data in Non-Coherent mode.

Abstract: A system for measuring a rise-over-thermal (RoT) characteristic in a communication network includes controlling a transmitting station to maintain its transmit power at a substantially constant level for a first time interval, and measuring a first received power level. The transmitting station is then controlled to adjust its transmit power by a selectable amount for a second time interval, and a second received power level is measured. The first and second received power levels are then processed to determine the RoT characteristic.

Abstract: A dynamic shared forward link channel (or "data" channel) is used to send multicast data to a group of wireless devices, e.g., using a common long code mask for the data channel. Reference power control (PC) bits are also sent on the data channel and used for signal quality estimation. A shared forward link control channel is used to send user-specific signaling to individual wireless devices, e.g., using time division multiplexing (TDM) and a unique long code mask for each wireless device. A shared forward link indicator channel is used to send reverse link (RL) PC bits to the wireless devices, e.g., using TDM. The data channel is jointly power controlled by all wireless devices receiving the data channel. The control and indicator channels are individually power controlled by each wireless device such that the signaling and RL PC bits sent on these channels for the wireless device are reliably received.

Abstract: An access point (e.g., a femto cell) that is connected in an active call with an access terminal may cooperate with that access terminal or another access terminal to derive timing information from one or more neighboring access points (e.g., macro access points). In addition, an access point may cooperate with an idle access terminal to derive timing information from one or more neighboring access points. For example, an access terminal may determine the difference between pilot transmission timing or frame transmission timing of a femto cell and a macro cell, and report this timing difference to the femto cell. Based on this timing difference, the femto cell may adjust the timing and/or frequency of its transmissions so that these transmissions are synchronized in time and/or frequency as per network operation requirements.

Abstract: A forward link repeater delay watermarking (FLRFWM) system and method that enable accurate position location of mobile stations in areas where repeaters are present by watermarking repeated signals with repeater information. A repeater watermarks a forward link signal with a (unique or non-unique) time delay modulation waveform watermark every time a signal passes through the repeater. A mobile station detects and/or identifies the time delay watermark on the forward link signal to determine repeater information that aids the network position determination entity or mobile station position location system in determining position location using AFLT and/or A-GPS systems. A forward link time delay watermarking system can be implemented to achieve low impact on FL and AFLT performance, favorable detection and identification probabilities, and short time-to-detect/identify.
