摘要： A wireless transmitter can include a plurality of bandwidth modules, each bandwidth module processing data based on a predetermined frequency band. In one embodiment, such a wireless transmitter can include encoding components for receiving transmit data and generating encoded data. A multiple-input multiple-output (MIMO) stream parser can receive the encoded data and generate a plurality of MIMO streams. A first module parser coupled to a first MIMO stream can generate a first plurality of partial MIMO streams. A first bandwidth module can include a first interleaver that interleaves bits of the first partial MIMO stream and generates first interleaved data. A second bandwidth module can include a second interleaver that interleaves bits of the second partial MIMO stream and generates second interleaved data. A first inverse fast Fourier transform (IFFT) unit can combine and process the first and second interleaved data and generate a first transmission MIMO stream.

摘要： A network coordinator can assign an association identifier (AID) and/or a group identifier (GID) to identify a client station to which a packet is to be transmitted and to enable the client station to determine whether to receive an incoming packet. The network coordinator can randomly generate a base AID that is representative of the network coordinator and can assign at least one AID to client stations to minimize the probability of client stations associated with proximate network coordinators being assigned the same AIDs. The network coordinator can also randomly assign at least one GID to a group of client stations to minimize the probability of groups of client stations associated with the proximate network coordinators being assigned the same GID. The client station can analyze indications of a received AID and/or received GID to determine whether to receive the packet or whether to switch to an inactive power state.

摘要： The position of a target wireless device in a wireless communication network can be calculated relative to a predetermined number of reference wireless devices in the wireless communication network to preclude the need for fixed/absolute reference points. The reference wireless devices can be selected based, at least in part, on comparing one or more performance measurements associated with each wireless device against one or more corresponding threshold performance measurements. The position of each of the reference wireless network devices relative to each other is determined based, at least in part, on a distance between each pair of the reference wireless network devices. The relative position of the target wireless network device is determined based, at least in part, on the position of each of the reference wireless network devices relative to each other and a distance between the target wireless network device and each of the reference wireless network devices.

摘要： Various methods and corresponding active interference cancellation units are described. These methods and units can perform active interference cancellation in a system including multiple radios. Notably, signals from a first radio can be received as interference at a second radio. The described methods and units can provide interference conditioning, which manipulates an interference reference of the interference at the first radio to approximate an interference observed at the second radio. After tuning of the interference conditioning, the interference can be removed.
