Abstract: Techniques are provided which may be implemented in various methods, apparatuses, and/or articles of manufacture for use by a device that is operable in a plurality of modes, including "higher power mode" and a "lower power mode". A timing circuit may be set based, at least in part, on a phase value obtained from a signal from a ground-based transmitter, and operation of the device may be selectively transitioned to a lower power mode wherein the device uses the timing circuit.

Abstract: Systems, methods and apparatus for configuring and accessing a random access channel in a CDMA communication system are disclosed. The number of users supported by a random access channel can be optimized by assigning a distinct time of arrival to each of a plurality of users. Each of the users can be time synchronized and can transmit data at a time that compensates for a propagation delay to allow the data to arrive at the destination receiver at the assigned time. In a CDMA system, each of the users can transmit data that is spread with the same spreading code, provided the cross correlation properties of the code are sufficient to allow identification of a source that is time offset relative to another user. The time of arrival can be determined based on the number of active users, and can be assigned as often as each transmission by each user.

Abstract: According to a disclosed embodiment, a first plurality of pilot signals of a first polarization is received (304) and ranked (306). Subsequently, a second plurality of pilot signals of a second polarization is received (308) and ranked (310). Following, a pilot signal from the first and second plurality of pilot signals is selected based on a signal quality measurement (312) such as a signal to interference ratio. Moreover, a system can be constructed comprising antennas (124, 126) configured to receive pilot signals of a first and a second polarization. The system further comprises a receiver (120) configured to demodulate the pilot signals and a CPU (112) configured to rank the pilot signals and to select a pilot signal based on a signal quality measurement. Communication quality is improved by communicating with the base transceiver station transmitting the pilot signal providing the highest signal quality measurement.

Abstract: Transmitter and receiver units for use in a communications system and configurable to provide antenna, frequency, or temporal diversity, or a combination thereof, for transmitted signals. The transmitter unit includes a system data processor, one or more modulators, and one or more antennas. The system data processor receives and partitions an input data stream into a number of channel data streams and further processes the channel data streams to generate one or more modulation symbol vector streams. Each modulation symbol vector stream includes a sequence of modulation symbol vectors representative of data in one or more channel data streams. Each modulator receives and modulates a respective modulation symbol vector stream to provide an RF modulated signal, and each antenna receives and transmits a respective RF modulated signal. Each modulator may include an inverse (fast) Fourier transform (IFFT) and a cyclic prefix generator. The IFFT generates time-domain representations of the modulation symbol vectors, and the cyclic prefix generator repeats a portion of the time-domain representation of each modulation symbol vector. The channel data streams are modulated using multi-carrier modulation, e.g., OFDM modulation. Time division multiplexing (TDM) may also be used to increase flexibility.
