摘要： A power management system and method for a wireless communication device generates an average desired transmit power signal based on at least one of a received signal strength indicator signal and a power control instruction signal from a base station. A power supply level adjustment signal is generated based on the data parameters of an outgoing data stream and at least one environmental information signal. A combination of the power supply level adjustment signal and the average desired transmit power or a gain control signal and an altered version of the power supply level adjustment signal is used to generate a variable power supply signal that is provided to an output amplifier block for sufficiently generating outgoing wireless device radio signals while reducing power loss in the output amplifier block.

摘要： In one illustrative example, a mobile station includes a wireless transceiver; a user interface including a Push-To-Talk (PTT) switch for initiating a PTT voice communication and a microphone for receiving voice input signals; one or more processors; and a First-In-First-Out (FIFO) buffer memory coupled to the one or more processors. The one or more processors are operative to identify a user actuation of the PTT switch and, in response, save digital voice data corresponding to voice input signals in the FIFO buffer memory; cause a request for the PTT voice communication to be made through a wireless network; identify that a floor grant has been received through the wireless network in response to the request; and after identifying the floor grant, cause the digital voice data from the FIFO buffer memory to be retrieved and transmitted to the wireless network for the PTT voice communication. Advantageously, the saving of the digital voice data in the FIFO buffer memory is performed at least in part during a delay time period between the user actuation of the PTT switch and the identifying of the floor grant.

摘要： An electronic circuit includes control circuitry, an analog-to-digital converter which includes a sampler, a pseudorandom noise (PN) generator configured to produce a PN signal, and a plurality of n correlators. The control circuitry is configured to control the sampler, in a sampling phase determination process, to sample a signal at a sampling period of T±T/n (where T is a symbol or chip period of the signal, and n is the number of phases of the sampled signal where n≧4) for outputting a sample set for each one of n phases of the sampled signal. Each correlator has a first input configured to receive one of the sample sets associated with a corresponding one of the n phases of the sampled signal, a second input configured to receive the PN signal, and an output which provides a correlation result from a correlation process between the sample set and the PN signal. The control circuitry is further configured to identify, from the correlation results, one of the phases associated with the optimal correlation result. The control circuitry is then configured to control the sampler, in a communication mode, to sample a received signal at a sampling period of T at the phase associated with the optimal correlation result, for use in recovering user or signaling information from the received signal.
