A frequency-designed fractional delay FIR structure, which is suitable for software radio applications, is presented. The design method is based on frequency optimization of a combination of modified Farrow and mutirate structures. As a result the optimization frequency range is made only in half of desired total bandwidth. According to the obtained results… (More)
Real time detection of moving objects from a video sequence has become an important role in computer vision field. Applications such as traffic control systems, surveillance systems, robotics vision and even more complex tasks such as human face recognition are currently subject of research. Although for some limited video applications the real time… (More)
This paper describes a reconfigurable hardware implementation for wideband fractional delay FIR filters. The proposed implementation is based on a multirate Farrow structure, reducing in this way the arithmetic complexity compared to the modified Farrow structure, and allowing on line fractional delay value update. A minimax frequency optimization technique… (More)
