The supremacy of software defined radio (SDR) technology in the field of cognitive radio (CR) is undeniable. In SDR, parameterisation is a very promising technique that consists of designing radio systems entities in a way which permits to take advantage of programmable or at least reconfigurable capabilities of the underlying hardware of SDR systems. In this paper, we describe linear feedback shift register (LFSR) as a common operator (CO) which is one of the first implementation of CO technique on the area of techniques of parameterisations. We explain our four developed common architectures to design 16 LFSR COs that can carry out several operations of multi-standard CR receivers. We also give the implementation details on Altera Cyclone II. Based on the foundation of the COs we describe a procedure which identifies an architecture that minimises the cost of the radio. Results obtained by optimisation validate the implementation results.
