Performance Analysis of Satellite-Terrestrial Network of Weibull Fading Channel

Unlike Rayleigh or Nakagami-m fading which has been widely studied in hybrid satellite-terrestrial relay network, the multi-branch Weibull fading which can be an alternative has been less studied due to its high intractability. In the proposed satellite-terrestrial Weibull system, by applying multi-branch optimal transmitting beamforming/receiving combination strategy, an upper bound of signal to noise (SNR) based outage probability (OP) is analyzed compared with the exact OP. Besides, two different methods are used to calculate the intractable Ergodic Capacity. Moreover, the closed-form expressions of the average symbol error rate (ASER) and Effective Capacity are hard to derive. Hence, simplified theoretical results of ASER and Effective Capacity are presented via the proposed upper bound of SNR scheme. Finally, various parameters are verified to illustrate the performance of the proposed model and demonstrate the effectiveness of our method.
