N2 - Physical layer security in slow fading wiretap channels is often guaranteed by constraining the secrecy outage probability (SOP) below a maximum tolerable value. In this paper, we propose a new nonadaptive (NADP) transmission scheme for maximizing the secrecy throughput by using adjustable transmit power based on the instantaneous channel state information (CSI) of the main channel under an SOP constraint. To solve this problem, we transform the optimization problem to single-variable maximization problems in two cases, and the quasiconcavity of them is proved which allows us to use the Golden Section Method (GSM) to find the optimal solution. Simulation results are provided and verify that the proposed NADP scheme is superior to the existing one especially when the transmit power is high.
