Systolic Array Based Adaptive Beamformer Modeling in SystemC Environment

Abstract

Optimal weight extraction of beamforming algorithms based on systolic structures have been the subject of various researches since the well-known article presented by Gentleman and Kung (1981) on recursive least squares systolic arrays. Systolic algorithms are parallel and fully pipelined structures, this feature improves the performance of the beamforming algorithms and the system. SystemC is a system design language, which was lately accepted by the IEEE as a standard. SystemC has the advantage of designing both the hardware and the software components together so that the design and simulation process of large systems become easier. This work is based on the simulation of the minimum variance distortionless response (MVDR) beamformer, proposed by Tang, Liu, and Tretter (1994), in SystemC environment and evaluate its performance
