摘要： A network device for cancelling spurs without affecting an incoming signal. The network device includes an estimator for estimating amplitude and phase of a spur over a predetermined period of time. The network device also includes processing means for freezing further estimation of the amplitude and phase of the spur, for cancelling for an estimated spur and for allowing incoming packets. The network device further includes subtracting means for subtracting the estimated spur from an incoming packet. The estimated spur is subtracted from the incoming packet without affecting incoming signals that are not part of the estimated spur.

摘要： Carrier detection applicable for SISO, MIMO, MISO, and SIMO communications. A novel approach is presented to perform carrier detection for a signal found in any of a wide variety of communication systems including single-input-multiple-output (SISO), multiple-input-multiple-output (MIMO), multiple-input-single-output (MISO) single-input-multiple-output (SIMO), communication systems. This novel approach to performing carrier detection is more robust than those approaches existent in the art. By employing normalization with respect to power in determined a modified correlation function, there is less susceptibility to false detects. Also, this approach is quite robust to any circuitry DC offsets that may undesirably exist within a communication device that undergoes operational changes due to a variety of factors including environmental perturbations and/or changes in processing circuitry within the communication device (e.g., changes in gain control).

摘要： A Wireless Local Area Network (WLAN) system in which wireless terminals each operate upon battery power. One of the wireless terminals acts as a Master to coordinate the transmission and receptions of the Slaves so as to reduce the power consumed by all of the devices. The Slaves operate according to a power up and power down sequence to conserve battery power. Further, the terminals may alternate between being Slaves and being the Master to equalize battery consumption of the wireless terminals.

摘要： New version packet data devices support a backwards-compatible signal format. New version devices operate within a first frequency band while old version devices operate within a second frequency band. The first frequency band differs from but overlaps with the second frequency band. The new version devices may operate on a first carrier frequency (within the first frequency band) while old version devices may operate at a second carrier frequency (within the second frequency band). The new version devices and/or the old version devices may also support carrier-less modulations. Preamble, header, and trailer portions of a new version signal include a plurality of spectral copies of a baseband modulated signal. One or more of these spectral copies of the baseband modulated signal is/are indistinguishable from corresponding components of an old version signal. The payload of the new version signal may be formed in the same manner or may be formed in have a wider bandwidth, higher data rate format.

摘要： A method of controlling power levels on a plurality of transmit streams in a single radio transceiver includes, for each of the plurality of transmit streams, detecting an output power level and sampling the output power level, digitizing the sample output power level, producing the digitized sample to a baseband processor. The baseband processor is operable to perform rate based compensation on the digital sample, to integrate and dump a plurality of digitized samples over a period that exceeds a transmission frame period to produce an average value over a specified number of samples. Thereafter, the processor is operable to convert the integrated plurality of digitized samples to a normalized value and to comparing the normalized value to a target value to generate a power index value to determine an output power level with rate based compensation.
