Abstract
A receiver system includes an interface between a radio receiver on a radio frequency (RF)-side and a baseband receiver on a baseband (BB)-side. The receiver includes an antenna for receiving radio frequency signals and an analogue-to-digital converter for converting received analogue signals to digital signals. The digital signals are further processed in the baseband receiver by a digital signal processing unit. The analogue-to-digital converter is a sigma-delta converter, which includes a sigma-delta modulator on the RF-side and a decimation filter on the BB-side. The sigma-delta modulator and the decimation filter are connected only by single-bit in-phase (I) and quadrature (Q) streams output lines.
