摘要： An improved automatic frequency correction acquisition system utilizes an automatic frequency correction (AFC) loop (22) having an acquisition mode in which an estimate of the frequency offset of a received carrier signal is rapidly acquired and a tracking mode in which the automatic frequency correction loop more accurately follows changes of the frequency offset. The AFC is switchable in response to predetermined control signals between the acquisition mode and the tracking mode. A carrier to impairment ratio estimator (36) is coupled with the automatic frequency correction loop (22) for estimating the carrier to impairment ratio of the incoming carrier signal. An automatic frequency correction controller (30) is coupled with the automatic frequency correction loop (22) and with the carrier to impairment ratio estimator (30) and is responsive to the carrier to impairment ratio estimate being at or above a preselected threshold value for producing a tracking control signal (24) comprising one of the predetermined control signals. The automatic frequency correction loop (22) is responsive to the tracking control signal (24) for switching from the acquisition mode to the tracking mode.

摘要： A method includes generating an indicator of interference introduced by a transmitter into a spectrum of an output transmit signal outside a target channel of the transmitter. The indicator is generated based on the output transmit signal. The method includes adjusting a power level of the output transmit signal based on the indicator and a predetermined interference indicator level. The indicator may indicate a carrier-to-interference (C/I) ratio of the output transmit signal, and the adjusting comprises setting the power level of the output transmit signal to a maximum power level that maintains the C/I ratio of the output transmit signal above the predetermined interference indicator level. The output transmit signal may be based on a radio-frequency output of a power amplifier of the transmitter prior to transmission over a channel and the generating comprises generating a baseband version of the output transmit signal.

摘要： The present invention provides a method for allocating channels in a wireless local area network (WLAN) among a plurality of clients. This method involves first assigning at least one client of the plurality of clients to a channel of a set of active channels. Next, for each client the access time is determined based on an access time factor. Assigning individual clients to channels further involves determining available channel capacity of the set of active channels and the desired channel consumption of the multiple clients. When the available channel capacity is equal to or greater than the desired channel consumption, multiple clients may be assigned to multiple channels. However, when the available channel capacity is less than the desired channel consumption, the desired channel consumption of the multiple clients is scaled to produce a scaled channel consumption wherein multiple clients are assigned to channels based on the available channel capacity of each of the set of channels and the scaled channel consumption.

The error mitigation unit may include a magnitude adjuster (220) for adjusting the input signal value (e.g., an ADPCM nibble) when the QI is less than a threshold, and a soft correction unit (240) for, when the QI is above the threshold, either soft correcting nibble magnitudes or muting selective nibbles based on further signal information such as differential phase.
