摘要： A Bluetooth detection unit can be implemented to minimize the time required for executing the inquiry and paging scan procedures on a Bluetooth device associated with a collocated WLAN device. The Bluetooth detection unit can execute concurrent background spectral scanning to detect Bluetooth control packets while the WLAN device is receiving WLAN packets. The Bluetooth detection unit can analyze, for each Bluetooth control channel, the Bluetooth device can determine energy measurements associated with each Bluetooth control channel and can determine whether each Bluetooth control channel comprises a narrowband signal based, at least in part, on frequency domain samples associated with an RF signal received at the WLAN device. The Bluetooth detection unit can determine which of the Bluetooth control channels comprise a Bluetooth control packet.

摘要： A method and apparatus for controlling an antenna array for wireless communication are described. The method uses the statistical characteristics of the received signal noise in controlling the antenna array in order to achieve directional reception in a wireless communication system and suppress co-channel interference. Furthermore, the method can be used to power space-division multiple access and can be used in conjunction with multi-carrier modulation signaling.

摘要： Systems and methods for processing received signals are disclosed and may include determining, for each block of data in a received frame, diversity combining weight vectors based on a channel estimate and a correlation matrix of an unwanted signal. For each sample in each of the block of data in the received frame, a corresponding one of the diversity combining weight vectors may be applied to extract a corresponding logic level. For the each block of the data in the received frame, a new correlation matrix of the unwanted signal may be generated based on the extracted corresponding logic level and the channel estimate, to process the received frame. The received signals may include a sequence of information data blocks, and each data block may include a plurality of samples. Each of the received signals may include an orthogonal frequency division multiplexing (OFDM) symbol and/or a multicarrier modulated symbol.
