摘要： Methods and systems for processing signals are provided and may include removing a DC component from a signal envelope comprising a combined signal within a range of allocated FM channels to generate a modified signal envelope. Fluctuation in power in the signal envelope may be detected based on a ratio of a magnitude of the signal envelope and a magnitude of the modified signal envelope. The removing may further include low-pass filtering the signal envelope to generate a low-pass filtered signal envelope. A square values of the low-pass filtered signal envelope may be determined to generate a squared signal envelope. The squared signal envelope may be high-pass filtered to generate a high-pass filtered signal envelope. The fluctuation in power in the signal envelope may be detected based on a ratio of a magnitude of the high-pass filtered signal envelope and a magnitude of the low-pass filtered signal envelope.

摘要： Certain aspects of determining a signal quality metric in event of a CRC false positive may comprise measuring an amplitude and/or phase of at least a portion of a phase shift keyed section of a frame. The measured amplitude and/or phase may be checked to determine if it lies within a range of a reference amplitude and/or phase respectively. An amplitude and/or phase counter may be incremented if the measured amplitude and/or phase lies outside the range of the reference amplitude and/or phase respectively. A confidence level value of a cyclic redundancy check (CRC) for at least a portion of the phase shift keyed section of the frame may be determined based on a determined value of the incremented amplitude and/or phase counter.

摘要： A communication system includes a conversion module configured to convert a signal between a radio frequency baseband (RF-BB) and an intermediate frequency (IF). At least one RF front-end module converts the signal between the IF and a radio frequency (RF). The RF front-end module is configured as an RF phased array and includes a coaxial interconnect configured to connect the conversion module with the RF front-end module. The signal is transmitted between the conversion module and the RF-front end module via the coaxial interconnect. At least one RF front-end module includes an active front-end (AFE) configured to allow the signal to be transmitted via the coaxial interconnect while minimizing any deterioration of the signal.

摘要： Techniques for localized dynamic channel allocation help meet the challenges of latency, memory size, and channel time optimization for wireless communication systems. As examples, advanced communication standards, such as the WiGig standard, may support wireless docking station capability and wireless streaming of high definition video content between transmitting and receiving stations, or engage in other very high throughput tasks. The techniques help to deliver the desired user experience in such an environment and address the need to meet latency and throughput requirements while limiting memory footprint.

摘要： Aspects of a method and system for multi-radio coexistence and a collaborative interface may include exchanging information between a plurality of radio transceivers integrated within a single device to enable coexistence, and coordinating sharing of transmit and receive resources between the plurality of radio transceivers by controlling access to the transmit and receive resources, where any one of the plurality of radio transceivers may be enabled to be selected to control the access based on the exchanged information. Selecting one of the radio transceivers for the controlling of the access band may be based on processing capability or priority of communication. The resources may comprise frequency bands, time slots, and antenna access. The information may be exchanged via a serial bus between the plurality of radio transceivers, where the serial bus may conform to an I2C (I-square-C) multi-master serial bus. Each of the radio transceivers may conform to one or more radio frequency technology.
