Using a TI C6701 DSP Rapid Prototyping System for Nonlinear Adaptive Filtering to Mitigate Interference

Abstract

Designing and implementing nonlinear systems, onto hardware devices experiences a paradigm shift with the innovative rapid prototyping system (RPS). The RPS is low cost, commercially off-the-shelf (COTS), and ingeniously establishes a direct path from initial design to a hardware implementation operating in real-time, eliminating several levels of tedious programming for hardware, with automatic code generation. In this paper, the hardware device is a digital signal processor (DSP) embedded in a prototype board. The RPS extends to real-world hardware testing specific to application, from which the nonlinear system design can be revised and optimized. From the RPS, final nonlinear system hardware can be designed with a high level of confidence, and the prototype board can continue to simulate other nonlinear devices. This paper explicates an overview of the RPS for nonlinear system hardware development. Section 2 addresses the nonlinear adaptive filter on the RPS for narrowband interference mitigation in communications channels. Section 3 conveys the overall RPS structure, procedure, and challenges overcome. Section 4 yields ideas for RPS expansion and concludes the paper.
