The effects of optical filter bandwidth on the received signal quality are discussed by analyzing bit error rate ( BER ) and contrast ratio performances. 通过分析比特错误率和对比性能讨论了光学滤波带宽对接收信号质量的影响。
With the ever-increasing requirements of high data rate and quality of service in wireless communication, many technologies have been proposed to improve the signal quality and the channel capacity, and to reduce the bit error rate ( BER ). 随着对无线通信服务质量和通信速率要求的不断增加,许多不同的技术被提出来以提高信号质量、增加信道容量和减少信息传输的误码率。
In this paper, the signal quality is improved via denoising in wavelet transformation domain, as a result the measuring error of stabilization precision is reduced. 本文利用小波变换对火炮误差角信号进行处理,改善了误差角信号的质量,有效减小了稳定精度的测量误差。
