A study of reconfigurable analogue for DRM and HF systems
Stuart Colsell · 2003
This paper focuses on the use of reconfigurable analogue technology to support multi-standard Digital Radio Mondiale (DRM) and high frequency (HF) communication systems. The choice of receiver architecture is discussed within the context of frequency adaptive systems and the low-IF receiver is introduced as an alternative to the zero-IF digital receiver. This paper also investigates the ability of field programmable analogue arrays (FPAAs) to implement matched filters within a low-IF receiver, thus providing the flexibility to support multistandard operation.
