Optimization of Multi-standards Software Defined Radio Equipments: A Common Operators Approach

Abstract : Parameterization is a very promising technique of Software Defined Radio (SDR) that consists of designing multi-standards radio systems entities in a way which permits to take advantage of the programmable or at least reconfigurable capabilities of the underlying hardware of SDR equipments. This thesis addresses the common operators' (COs) technique for parameterization. COs are processing commonalities between operations of an equipment whatever the Open System Interconnection (OSI) layer may be. The method proposes a theoretical approach to solve the design issue of multi-standards radio equipments. It consists in a hypergraph's optimization. The equipment design is represented with operators of several levels of granularity in a directed acyclic graph. Top level represents a Velcro way of designing multi-standards equipment. The lower, the operators in the graph, lower is their cost in terms of complexity but higher is the number of times they are called to perform the operations of different kinds and vice versa. As examples we describe the design and use of dual mode fast Fourier transform (DMFFT), linear feedback shift register (LFSR) and frequency response masking filter bank (FRMFB) as COs. The proposed solutions in this thesis which are based on CO technique can help an SDR designer to optimize the design of future SDR equipments that are required to support a wide range of existing and future wireless technologies and services.
