中文摘要：
针对无线射频识别系统在通信过程中的防碰撞问题,从信号处理的角度,提出一种基于盲源信号并行分离技术的防碰撞处理算法,其中包括信号白化技术,以及一种改进的独立元分析（ICA）信号并行分离方法。功能仿真结果证明,该算法的吞吐率最高达到69%,与吞吐率只有18%的传统Aloha算法相比,该算法能提高防碰撞能力。
英文摘要：
To solve the Radio Frequency Identification（RFID） data anti-collision problem in communication,a new anti-collision algorithm,from the anti-collision angle of signal processing,is proposed based on blind source separation technology of signal parallel,including signal white technology,and an improved Independent Component Analysis（ICA） signal parallel separation algorithm.Function simulation results show that the new algorithm＇s throughput rate is to 69% of the highest,and compared with only 18% of throughput rate Aloha algorithm,the new algorithm improves the ability of anti-collision.
