    摘要: A data module operable in a wireless communication system is provided. The data module comprises a plurality of circuit components, one or more temperature sensors, and a thermal management unit. The temperature sensors are configured to determine the temperature of a corresponding circuit component. The thermal management unit is configured to determine one or more thermal characteristics of the data module based on the temperature determinations, and to generate one or more power control point signals indicating whether to adjust corresponding operating characteristics of a target component based on the determined thermal characteristics.

    摘要: A Wireless Code Division Multiple Access method and apparatus for determining the transmitted rate of a voice/data signal from a mobile station to a Base Station. Variable rate vocoders transmit voice at one of several predetermined frame rates. The receiver determines the transmitted rate based on one of several frame parameters. One of the parameters is received frame energy. The received frame energy is measured over the length of the relevant portion of the frame. Energy is measured over the half of the frame that can only contain energy if a full rate frame is sent. If the energy measured exceeds a threshold, then full rate is indicated. Else, energy is measured over the fourth of a frame that can only contain energy if a half rate frame is sent. If the energy exceeds a threshold, then half rate is indicated. The procedure is repeated for quarter and eighth rates.

    摘要: In order to time track an incoming signal, a receiver demodulates a first instance of a signal to produce a first set of energy values corresponding to a set of possible data values of the signal (200, 270). The receiver also demodulates a second instance of the signal to produce a second set of energy values corresponding to the set of possible data values (208, 272). The receiver combines the first and the second sets of energy values to determine a combined set of energy values (210, 276). The receiver determines a first estimate of a most likely transmitted data value based upon the combined set of energy values (202, 278). The receiver decovers an early set of despread samples of the first instance using a symbol corresponding to the first estimate to produce a first early energy value. The receiver decovers a late set of despread samples of the first instance using the symbol corresponding to the first estimate to produce a first late energy value (214, 284). Finally, the receiver determines a time offset of the first instance based upon the first early and the first late energy values.

    摘要: A wireless receiver receiving multipath Walsh-code symbols determines which of fingers (402, 410) have locked on a signal. Measurements of the correlation energies between the received signal and all possible symbols are stored in energy storage units (404, 412). The actual signals are combined in combiner (408). A maximum determiner (416) determines the most likely combined symbol, and an index for this symbol is fed back to the energy storage units. Lock detectors (406, 414) use the measurement for this fed-back symbol to determine whether the finger has locked onto a path. This determination is used to decide whether the next signal detected by that finger should be applied to the combiner.

    摘要: A method and apparatus for compressing fixed point signals without introducing a bias. Signals are compressed according to a dithered rounding approach wherein signal values are rounded up and rounded down with approximately equal probability, canceling the bias that would otherwise result from the rounding operation. Numerical properties of the input signal are exploited in order to determine whether the signal value should be rounded up or down. Signal compression may, therefore, be introduced at multiple points within a system without accumulating a signal bias and degrading downstream performance. Further, one bit signal compression may be achieved in a particularly efficient fashion with a minimal amount of hardware.
