摘要： In some wireless local area networks (WLANs), signals of different modulation types and rates can be received. To operate optimally, the gain of an amplifier in a receiver can be set based on a specific modulation type and rate. For example, the gain of a receive path amplifier can be changed based on one or more unique identifying characteristics in a received data packet. Once the unique identifying characteristics are located, they can be analyzed to determine which modulation type and rate are represented. The appropriate gain of the amplifier can be set based on the modulation type and rate. Advantageously, subsequent data symbols can be amplified with the set gain, thereby ensuring that the receiver optimally receives those data symbols.

摘要： A method and system for reducing the DC offset in a receiver in the presence of carrier frequency offset between the transmitter and the receiver. The present invention utilizes the knowledge of the carrier frequency offset to determine the phase difference between two (or more) snapshots of the same transmitted symbol. The receiver DC offset is solved for using a linear system solver which can be implemented outside the analog domain. The DC offset may be tracked in order to maintain a constant adjust of the DC offset, which in combination with the above DC offset estimation technique implements a complete solution for the DC offset cancellation problem.

摘要： A communication system such as an OFDM or DMT system has nodes which are allowed to transmit continuously on one or just a few of the sysiem's frequency sub-channels, while the other nodes avoid putting any signal into those sub-channels. Simple low data rate nodes are allowed to use a small number of sub-channels while more complicated nodes use the remainder, and preferably functionality is provided to ensure that adjacent sub-channels are reliably spaced apart in frequency so that they do not bleed over into one another; to ensure that signals from all nodes arrive at the base station with well-aligned symbol transitions; and to ensure that signals from the various nodes arrive at the base station with similar power levels.

摘要： The present invention provides an apparatus and method for optimizing power in order to increase capacity. Rather than having any terminal device limited to a specific maximum data rate, instead the terminal device data rate is limited by the power being used, such that the data rate can vary according to the distance that the terminal device is from the intended receiver.

摘要： Circuits, devices and methods for processing learning networks are implemented using a variety of methods and devices. One example involves a circuit-implemented method to identify a relationship of objects in a set of objects. Local scores are generated for the object and possible parents. The local scores indicate relationship strength between object and parent. The results are stored in a memory. A state-machine circuit is used to perform sampling and searching of the parent sets for each data node. The local scores are used to encode orderings of the parent. An algorithm is executed that uses the encoded possible orderings and a random variable to generate and score a current order and a proposed order of the possible parent sets. The proposed orders are accepted or rejected based on probability rules applied to the scores for the current and proposed orders. Structures are sampled to assess a Bayesian-based relationship.
