Abstract

This paper proposes a unique algorithm to control the parallel NCO overflow mechanism

which is applied to the digital parallel resampling module in the high-rate broadband system. It can issue the accurate interpolation position and overflow enable in a parallel NCO of the digital resampling module from a simple rule: Judge from sign. Consequently

a parallel digital resampling module based on algorithm above is implemented on the typical construct of interpolation filter. Simulation results show that the parallel NCO control algorithm executes a fine interpolation performance

and a hardware application on a general logic platform shows its high portability and flexibility.
