摘要： A system can comprise a radio unit. The system can further comprise a power detector that is configured to determine characteristics of incident signal data traffic of the radio unit. The system can further comprise an actuator that is configured to modify an operational parameter of the radio unit, wherein modifying the operational parameter of the radio unit alters performance of the radio unit. The system can further comprise a hardware component that is configured to cause the actuator to modify the operational parameter of the radio unit based on analyzing the incident signal data traffic.

摘要： Certain aspects of the present disclosure provide a method for wireless communications by a wireless device. The wireless device evaluates a plurality of antenna group combinations based on one or more criteria wherein each antenna group combination includes at least two antenna groups of multiple antennas and the one or more criteria involve a first performance value calculated separately for each antenna group in an antenna group combination under evaluation and a second performance value calculated collectively for the at least two antenna groups in the antenna group combination under evaluation. The wireless device selects a subset of the plurality of antenna group combinations, based on the evaluation.

摘要： The present disclosure provides a method and system for testing wireless performance of a wireless terminal configured as a DUT having multiple transmitting antennas and placed in an anechoic chamber. The method includes: obtaining antenna pattern of the multiple transmitting antennas, and importing the antenna pattern into a channel emulator; selecting a same number of testing antennas in the anechoic chamber as a number of the transmitting antennas; the selected testing antennas receiving a signal from the transmitting antennas, and sending the signal to the channel emulator, the channel emulator processing the signal to generate an analog signal and sending the analog signal to an analog base station; and the analog base station receiving the analog signal and performing a throughput test to obtain an uplink wireless performance test of the DUT.

摘要： A tentative decision is made for symbols on the basis of a received signal and a decision threshold, and a tentative decision signal including a sequence of the symbols is output. A scale value indicating a rate of increase or reduction of the received signal or a threshold change rate indicating a degree of change in the decision threshold is updated so that an appearance frequency of each of symbols included in the tentative decision signal matches an appearance frequency of each of symbols in a reference signal obtained by modulating a transmitted signal with a modulation method used in transmission which is shared between a transmitting side and a receiving side, and an SN ratio is calculated using the scale value or the threshold change rate when a degree of agreement between the appearance frequencies is within a predetermined permissible range. When the scale value is updated, a tentative decision is made for the symbols on the basis of the received signal increased or reduced by the updated scale value and the decision threshold, and when the threshold change rate is updated, the tentative decision for the symbols is made on the basis of the received signal and the decision threshold to which the updated threshold change rate is applied.

摘要： An over-the-air measurement system for testing the over-the-air characteristics of a device under test is described, comprising several antenna units for receiving and transmitting radio frequency signals, several remote radio units that convert radio frequency signals into digital signals or vice versa, and a baseband unit for generating and analyzing baseband signals. The baseband unit is connected to the remote radio units, the baseband unit having at least one physical layer control unit that is configured to adapt the over-the-air measurement system with regard to the physical layer. The several antenna units are connected to the remote radio units. Further, a method for testing the over-the-air characteristics of a device under test is described.

摘要： Systems and methods for design and testing of RF components are described. One or more RF isolation chambers are used to house MU-MIMO capable devices under test, including wireless access points and client devices. Spatial and angular positioning of the antennas within a chamber and controlled power of the signals into each antenna via RF combiners and RF attenuators to achieve a controllable apparent/virtual angular spread among the respective client device signals is described.
