Abstract: An antenna system for a mobile communications base station and a method of operating a communications network including a base station is described. The antenna system includes an antenna array for beamforming and is configured either as a radar sensor, a communications antenna or a combined radar sensor. A radar image may be used to determine a map of objects in the vicinity of the antenna system and to adapt the beam-steering or beamforming of the antenna system.

Abstract: An analog-to-digital converter including a converter arrangement configured to provide a digital output signal as an output of the analog-to-digital converter based on an analog input signal comprising an input to the analog-to-digital converter, the analog-to-digital converter including a calibration module configured to provide calibration signalling to set one or more of a gain of one or more components of the converter arrangement and an offset of one or more components of the converter arrangement, the calibration module further configured to provide, as an output, diagnostic information based on the calibration signalling for use in determining the occurrence of a fault in the analog-to-digital converter.

Abstract: A frequency estimation signal generator component arranged to receive an input frequency signal and to generate therefrom a frequency estimation signal. The frequency estimation signal generator component comprises a counter component arranged to sequentially output a sequence of control signal patterns over a plurality of digital control signals under the control of an oscillating signal derived from the received input frequency signal terns. The frequency estimation signal generator further comprises a continuous waveform generator component arranged to receive the plurality of digital control signals and a weighted analogue signal for each of the received digital control signals, and to output a continuous waveform signal comprising a sum of the weighted analogue signals for which the corresponding digital control signals comprise an asserted logical state. The frequency conversion component is arranged to derive the frequency estimation signal from the continuous waveform signal output by the continuous waveform generator component.
