Abstract :
A custom DSP chip for mobile radio systems like the American IS-54 system is presented. The application is a digital intermediate frequency filter which is intended to replace expensive analog filters. It is a lattice wave digital filter with fixed coefficient bit-serial arithmetic. A technique which is useful for area efficient layouts in high throughput real time signal processing is discussed
