Abstract :
A new optimal, efficient filter design synthesis for interpolation filters suitable for software-defined radio receivers is presented. The proposed cost function takes into consideration the desired time and frequency responses as well as the symbol timing error, suitable for practical design objectives. Illustrative filter design examples are given and their performance are compared with that of other similar interpolators with a similar complexity. Simulation results show that the new interpolators outperform others.
