The performance evaluation in the case of communication radio networks is different from that the single-link communication. The formation of complex heterogeneous communication networks due to the different levels of communication makes the lack of a unified and systematic assessment framework in terms of assessment principles, criteria, methods and evaluation index systems. According to the network...
The intermodulation interference of communication radio affect the normal communication, in which the third-order intermodulation interference can not be avoided. In this paper, the signal characteristics of the third-order intermodulation interference are studied, and the envelope expression of the third-order intermodulation products of different modulation styles and the mathematical expression...
The method of mutual coupling correction of array output signal is studied in the paper. According to array signal processing's feature, array error model is analyzed and array mutual coupling is studied. The method that smart antennas' channel calibration by BP network in wireless communication is proposed, which improves the accuracy of algorithms, such as the DOA estimation algorithm, Beam Forming...
There are always some errors based on nonlinear equation by choice different models in propagation loss prediction. A prediction method for propagation Loss in VHF based on BP neural network is proposed, and the model structure of BP network is designed. Then the propagation loss in VHF is predicted using the measured data of the different terrain. The results show that the prediction accuracy of...
