摘要： A radiowave propagation estimation device uses identification information enabling an object including a structure to be identified, and map data including the structure, to extract a structure of the object which is visible from both a direct or pseudo transmission point of radiowaves and a direct or pseudo reception point of the radiowaves, on the basis of the identification information. The radiowave propagation estimation device estimates a propagation characteristic of the radiowaves by using information indicating a characteristic of the extracted structure of the object.

摘要： The present invention discloses a parameter obtaining method and apparatus, so as to resolve a problem that manual analysis of a received-signal constellation diagram is not applicable to a higher-order quadrature amplitude modulation QAM scheme, and an analysis result depends on an technical level. In this method, multiple signals are received over a communications link on a network, where each of the received signals is corresponding to a point on a complex plane; decision is performed on each of the received signals, so as to obtain a decision signal; for each of the received signals, an error signal between the received signal and a corresponding decision signal is determined; and a complex-plane distribution feature parameter used to indicate a distribution feature, on the complex plane, of the signals received over the communications link is determined according to all the determined error signals. In this method, maintenancean inaccurate maintenance result in manual analysis of a constellation diagram is avoided, and in addition, there is no modulation order restriction because the complex-plane distribution feature parameter is obtained by using the error signals.
