Abstract :
A new sample rate conversion (SRC) method for software radio (SWR) systems is proposed. The method, which uses the window filter design and Lagrange functions, requires fewer computations than other SRC methods over a range of SRC factors for the wideband and high dynamic range signals that are typical of SWR systems. The computational requirements of the proposed SRC method and other SRC methods are compared and simulation results of the proposed method are discussed.
