摘要
本文分析了在单反射波和多反射波存在时情况下的DVB64/256QAM接收机的性能。试验结果表明,当反射波幅度达到—7dBc时能够由接收机可靠地补偿。测量结果与基于一种改进的有效最小均方(LMS)算法的计算机模拟十分吻合。
The performance of a DVB64/256QAM receiver in the presence of single and multiple echoes is analyzed. Experimental results indicate that echo magnitude as large as--7dBc can be reliably equalized by the receiver. The measured results are in excellent agreement with computer simulations based on amodified computationally efficient LMS algorithm.
