    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： Aspects of a method and system for Bluetooth 802.11 alternate MAC/PHY (AMP) transmit power control (TPC) may include one or more processors, receiver circuits and/or transmitter circuits that are operable to determine a maximum input level based on signals received via a Bluetooth basic rate (BR) connection and/or via a Bluetooth extended data rate (EDR) connection. The processors and/or circuits may be operable to determine a transmitted signal power level based on the determined maximum input level. The processors and/or circuits may be operable to transmit subsequent signals via a distinct Bluetooth connection based on the determined transmitted signal power level. The data rate for signal transmission via the distinct Bluetooth connection may exceed the data rate for signal transmission via the BR connection and the data rate for signal transmission via the EDR connection.

    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.

    摘要： In a radio comprising a transmitter and a receiver, transmission and reception of signals may be controlled based on received signal strength measurements from a signal strength indicator module and transmitted signal strength measurements from the signal strength indicator module. For the transmitted signal strength measurements, the shared signal strength indicator module may measure signal strength of a signal output by a power amplifier. For the received signal strength measurements, the shared signal strength indicator module may measure signal strength of a received signal. A capacitance coupled to an output of the power amplifier may be configured based on a frequency of the signal output by the power amplifier. A gain of the power amplifier may be controlled based on the transmitted signal strength measurements. For the transmitted signal strength measurements, an analog-to-digital converter may process the signal output by the power amplifier.

    摘要： Methods and systems for optimal frequency planning for an integrated communication system with multiple receivers may include adjusting a center frequency of a low IF signal to reduce interference by a second order interference signal. The center frequency may be adjusted to avoid high power portions of the second order interference signal. The interference level corresponding to a center frequency may be determined by, for example, a SNR of the low IF signal, or by determining a BER for the low IF signal. The center frequency of the low IF signal may be dynamically adjusted to keep second order interference level at an acceptable level. Adjusting the center frequency of the low IF signal may also comprise keeping the low IF signal from being blocked by a DC component of the second order interference signal.
