摘要

设计了基于宽带码分多址(WCDMA) 3GPP标准的遥控空中系统(RPAS)通信信道模型。考虑了无线瞄准线(RLoS)内基站(BS)传输和利用超无线电瞄准线(BRLoS)通过卫星的传输。得到了不同RPAS速率和WCDMA 信道模型下误码率(BER)与信噪比的关系。研究了不同程度的卫星转发器非线性情况下误码率与信噪比的关系。分析了在转发器非线性情况下，误码率与BS天线直径的关系。卫星信道特性的依赖关系，首先考虑到RPAS的运动，使得在关键条件下预测通信系统的行为成为可能。

RPAS COMMUNICATION CHANNELS BASED ON WCDMA 3GPP STANDARD

First built models of Remotely Piloted Air System (RPAS) communication channels based on Wideband Code Division Multiple Access (WCDMA) 3GPP Standard were designed. Base Station (BS) transmission within the Radio Line of Sight (RLoS) and through the satellite using Beyond Radio Line of Sight (BRLoS) was considered. The dependencies of the Bit Error Rate (BER) on the signal-noise ratio for different RPAS velocities and WCDMA сhannel models were obtained. The dependences of the BER on the signal-noise ratio for different levels of satellite transponder nonlinearity were studied. The dependence of the BER on the BS antenna diameter in case of the transponder nonlinearity was analysed. The dependencies for satellite channel characteristics, first obtained taking into account the motion of the RPAS, make it possible to predict the behavior of the communication system in critical conditions.
