基带传输系统码间干扰及其消除问题讨论

Discussion on the Problems on ISI(Inter-symbol Interference) in the Base-band Transmission System and Their Elimination

以基带传输系统为例,给出码间干扰的概念,并推导出系统无码间干扰的条件——奈奎斯特第一准则,并通过算例探讨了奈奎斯特准则的应用。

Taking the base-band transmission system as the example, this paper gives the concept of ISI, and deduces the condition of non-inter-symbol interference of system - Nyquist 1 criteria, and probes into the application of Nyquist criteria with exarnples.
