We present an approach for analysing and improving fault-tolerance aspects in radio architectures. This is a necessary step to be taken in order to implement reliable radio systems in future nanoscale technologies. We present problem formulation, optimisation approach and implementation methodology. We are adding fault tolerance at architecture-level by taking advantage of existing parallel structures and using a spare module approach in order to minimise hardware overhead needed. These issues have been analysed and demonstrated using two radio case studies: a UMTS MIMO and a GSM diversity receivers.
