Study on Shortwave Signal Coverage Based on ITU-R P.533 Model

In order to overcome the limitations of traditional road test methods in 5G mobile communication network signal coverage detection, a signal coverage detection algorithm based on distributed sensor network for 5G mobile communication network is proposed. First, the received signal strength of the communication base station is collected and pre-processed by randomly deploying distributed sensor nodes. Then, the neural network objective function is modified by using the variogram function, and the initial weight coefficient of the neural network is optimized by using the improved particle swarm optimization algorithm. Next, the trained network model is used to interpolate the perceptual blind zone. Finally, the sensor node sampling data and the interpolation estimation result are combined to generate an effective coverage of the 5G mobile communication network signal. Simulation results indicate that the proposed algorithm can detect the real situation of 5G mobile communication network signal coverage better than other algorithms, and has certain feasibility and application prospects.

Critical Aspects

As a replacement for the Loran A systems installed on approximately fifty B-707/300 aircraft and to have this replacement fully operational by the end of 1977 only two options were available: the very well proven but relatively costly inertial systems and the almost totally unproven but potentially much less costly Omega. Economic considerations played a major role in this choice in view of the limited remaining useful life of the aircraft involved. The general object of the programme was to assess the acceptability of Omega as a pilot-operated substitute for Loran A in aircraft also equipped with dual doppler/computer navigation systems. Critical aspects of the use of Omega which were to be investigated were:(i) the availability of adequate Omega signal coverage on a reasonably worldwide basis,(ii) the normal in-lane accuracy of the Omega position output,(iii) the in-lane stability of the Omega position output, i.e. susceptibility to ‘lane-slip’,(iv) the reliability of the airborne Omega hardware,(v) the operational suitability of the control/display units.
