摘要：

Based on the principle of delay-and-sum beamformer, a four channel speech enhancement design scheme was proposed. Here the principle of designed hardware and software was introduced. Hardware design includes singlechip, digital-to-analog and analog-to-digital converter, electrocircuit connect and so on. In design software run in real time is a very important problem. In order to solve the problem, the method combined software and hardware is adopted. Ring buffer technology is used too. Experiment result show the proposed scheme is effective.
