摘要： Methods and apparatuses for attenuating an interferer signal are provided. The apparatus includes a tunable filter and an autonomous tracking control circuit. The tunable filter is constructed to receive signals within a frequency bandwidth and includes a plurality of tunable bandpass filters with respective bandpass filter responses. The tunable filter has a band reject filter response that is dependent upon the bandpass filter responses. The autonomous tracking control circuit is constructed to track an interferer signal within the frequency bandwidth and perform voltage control on the plurality of tunable bandpass filters to alter the band reject filter response of the tunable filter such that the interferer signal is attenuated in an output of the tunable filter.

摘要： This application provides a communication device, including: a first radio frequency unit, a second radio frequency unit, a switch control unit, and a first signal processing channel. The first signal processing channel includes a first analog-to-digital conversion unit, a first intermediate frequency channel unit, and a first baseband processing unit. The switch control unit is configured to determine, based on resource control information, to connect the first radio frequency unit or the second radio frequency unit to the first signal processing channel. A first radio frequency band in the first radio frequency unit is different from a second radio frequency band in the second radio frequency unit. In this way, different frequency bands may share one radio frequency signal processing channel, thereby optimizing a processing channel, reducing costs, and miniaturizing a communication design.

摘要： Methods and devices for limiting the power level of low noise amplifiers (LNA) implemented in radio frequency (RF) receiver front-ends. The described methods are applicable to bypass, low and high gain modes of the LNA. According to the described methods, the decoder allows the signal to be clamped before or after being attenuated. The benefit of such methods is to improve large signal performances (e.g. IIP3, P1dB) of the RF receiver front-end, while still meeting the clamping requirements, or improve (lower) clamped output power, while still meeting large signal performances (e.g. IIP3, P1dB).

摘要： A distributed radio frequency communication system includes a remote radio unit (RRU and a baseband unit (BBU) and facilitates communication between a wireless terminal and a core network. The RRU receives a radio frequency signal from a wireless terminal and convert the radio frequency signal to digital baseband samples using receiver circuitry and an analog-to-digital converter. The RRU then adaptively compresses the digital baseband samples, using adaptive compression circuitry, to create fronthaul uplink information, and sends the fronthaul uplink information over a fronthaul link to the BBU using an adaptive fronthaul protocol. The RRU also receives fronthaul downlink information over a fronthaul link from the BBU using an adaptive fronthaul protocol and generates frequency-domain samples, based on the fronthaul downlink information received. It then creates time-domain baseband samples from the frequency-domain samples and converts the time-domain baseband samples into a radio frequency signal to send to the wireless terminal.

摘要： A high-speed data receiver includes interleaver circuitry configured to divide a received data stream into a plurality of interleaved paths for processing, spectral content detection circuitry configured to derive spectral content information from data on each of the plurality of interleaved paths, sorting circuitry configured to bin the derived spectral content information according to energy levels, stream attribute determination circuitry configured to determine, based on sorted spectral content, one or more of path offsets of the interleaved paths, gain mismatch among interleaved paths, signal bandwidth mismatch and pulse width mismatch, and equalization circuitry configured to correct the one or more of the determined offsets, the determined gain mismatch and the determined signal width mismatch. Equalization circuitry may be configured to equalize a gain-normalized signal by separately adjusting respective bandwidth actuators of each respective interleaved path and respective pulse width actuators of each respective interleaved path.
