摘要

In this paper, we propose a new design of radio link for Unmanned Aerial Vehicles (UAVs) with respect to the symbol error rate (SER), Alamouti coding and space time block code (STBC)of M-ary θ-quadrature amplitude modulation (QAM) i.e. Square-QAM (SQAM) and Triangular-QAM (TQAM) in presence of additive white Gaussian noise (A WGN) and channel fading in a MIMO radio link. Moreover we consider the error performance of the regular triangular/square quadrature amplitude modulation. In particular using an accurate exponential bound of complementary error function, we determine an approximation for the symbol error rate of T/S-QAM over A WGN in the fading channels. At the end some simulation results verify our theoretical results and we compare our work with other research.
