本文旨在提供一个民用无线通信业务可接受的实用信道设计方法。它是在电波传播路径剖面图绘制基础上，以稳定通信业务（话音、数据）为目标，在固定通信点对点广义连续信道上进行的。为了实际设计与评价一条待开通的电路，本文选用了一些图表资料及有关建议，它们都是很有权威性的。考虑到无线电干扰的严重影响，本文也涉及了有关人为噪声，同道及邻道干扰引起的通信质量下降及其对策问题。 The purpose of this paper is to provide an acceptable practical channel design methodology for civil wireless communications services. It is in the radio propagation path profile based on drawing, to stabilize the communication services (voice, data) as the goal, in the fixed point-to-point communication on the generalized continuous channel. In order to actually design and evaluate a circuit to be opened, this paper selected a number of chart data and related recommendations, which are very authoritative. Considering the serious impact of radio interference, this paper also deals with the problem of communication quality degradation and countermeasures caused by man-made noise, fellow channel and adjacent channel interference.
