  • Patent number: 9806921
    Abstract: A mobile communication device is provided that includes a receiver configured to receive a signal. The communication device further includes a calculation circuit configured to determine a cumulant value of an order higher than two of the received signal, to determine a function value of the determined cumulant value and to compare the determined function value with a predefined value. The communication device further includes a decoder configured to decode the received signal. The communication device further includes a target signal detector configured to activate the decoder based on the comparison of the function value with the predefined value.

  • Patent number: 9743399
    Abstract: Generally, embodiments to enable, indicate and detect Short Interframe Space (SIFS) of different time durations, a short (or small) SIFS which is shorter in duration than a regular SIFS, are described herein. Embodiments may comprise logic such as hardware and/or code to signal a short SIFS or a regular SIFS by setting or clearing a bit of a management frame transmitted by a station to an access point during the network association process, or by setting or clearing a bit in the SIG field of the preamble of a data unit transmitted by an access point to an associated station. In some embodiments, a third party station is able to receive the data unit sent by the access point, and decode, e.g., the SIG field bit to determine whether the short SIFS duration or regular SIFS duration is defined for the communication between the access point and the station.

  • Patent number: 9559810
    Abstract: According to various aspects of the present disclosure, medium access control (MAC) sublayer logic of a device or a system may generate and implement a preamble structure of a data unit including a signal field which includes a four-bit cyclic redundancy check sequence providing a Hamming distance of two. The signal field portion of the preamble structure may include information related to a plurality of physical layer parameters used for wireless communication of the data unit. The preamble structure may be stored on a machine-accessible medium. The preamble may be generated by a data unit builder of the device, which may further receive a frame including a data payload, and encapsulate the frame with the preamble portion to generate the data unit. A transmitter coupled with the data unit builder may then wirelessly transmit the data unit using an antenna array.

  • Publication number: 20140177764
    Abstract: Wireless systems, devices, and methods are presented in which a communications interface unit is configured to receive a wireless signal and includes a first channel path having a first down-converter to generate a first analog baseband signal and a first ADC to generate first digital samples as well as second channel path having a second down-converter that operates at a frequency orthogonal to the first down-converter and generates a second analog baseband signal and a second ADC to generate second digital samples. In addition, a packet detector unit is used to detect a beginning frame of packet data, wherein the second channel path is deactivated until the beginning frame of the packet data is detected and the packet detector detects the beginning frame of the packet data based on only the first digital samples provided by the first channel path.
