摘要
介绍基带和频带传输系统中常见码间串扰问题消除方法，通过理论分析，比较两种传输系统无码间串扰时的频带利用率，以便学生对频带利用率的正确理解和求解此类问题时简化运算。
In this paper, the elimination of ISI problems, which are common in base-band and frequency band transmission systems, is introduced. By theoretical analysis, the bandwidth efficiency of the two systems are compared when ISI problems do not exist. The results can help students have correct understanding of the bandwidth efficiency and simplify the computation in solving such problems.
