FPGA realization of energy detection based on simulation system

Hardware-in-the-loop (HIL) simulation has been widely used in systems development and algorithm verification in many fields. This paper presents a simulation system by using this method in the field of wireless communication. The simulation system is composed of control panel, software module and hardware module. Distribute interactive simulation, collaboration between different subsystems and data security can be accomplished through main control and management. In the part of hardware, we design Ethernet-oriented protocol for module communication and control executive module realized in FPGA (Cyclone IV 4CE115). At last, we introduce energy detection algorithm based on Neyman-pearson criterion which is verified in this system. The result shows that simulation system can accomplish complex simulation by means of data and resource analysis and parameter optimization in real time.
