全数字式自适应均衡器是4800bit/s数据传输系统的一部分。一般自适应均衡器的启动时间大约几百毫秒或几秒钟。现在提出一个在高速同步数据通信中所使用的自适应横向滤波器快速启动的新技术。使用一个特殊的训练序列,它的符号周期,等于均衡器抽头数目。这训练序列可以用来实现初始的眼图张开。自适应均衡器的初始收敛不用首先建立同步,就可很快实现。本文叙述了这个系统的计算机模拟方法,并给出计算机模拟的结果。这些结果说明了上述方案是可以实现的。最后文章给出了由计算机模拟所确定的这个系统的主要参数。 Fully digital adaptive equalizer is part of the 4800bit / s data transmission system. General adaptive equalizer start-up time of about hundreds of milliseconds or seconds. A new technique for fast start-up of an adaptive transversal filter used in high-speed synchronous data communications is now proposed. Using a special training sequence, its symbol period equals the number of equalizer taps. This training sequence can be used to achieve the initial eye opening. The initial convergence of the adaptive equalizer can be achieved quickly without first establishing synchronization. This article describes the computer simulation of this system, and gives the results of computer simulation. These results show that the above solution is achievable. The final article gives the main parameters of the system as determined by computer simulation.
