Abstract

Considering the coding-excitation technology applied in ultrasonic systems, pre-decoding by multi-center before beam-synthesis is recognized as the best method for decoding. Compared with the method of decoding after synthesizing, the former avoids the inferior quality of side-lobe performance invited by beam-synthesis (the attenuation is more than 15dB). However, it is restricted by its great requirement to hardware cost resources so that pre-decoding method couldn't be made the most of in practice. In order to resolve the practical issue, this paper advances a set of project to retrench hardware cost by optimizing the decoding algorithm in theory. The resulting data based on Golay code with Quartus II validates the validity and feasibility of this project.
