The performance of wireless communication system in complicated electromagnetic environment is difficult to evaluate. Building a simulation platform in HLA architecture seems to be a good solution. Transmitting flow, reception flow and interaction strategy are discussed to fit the mechanism of pRTI. By the way of low-pass equivalent, the reduced data rate of signals is suitable for software simulating,...
Aiming at the tight coupling features between system and modules in the distributed application system that implemented with components, the paper brought out an Event Process Framework (EPF), which achieves information interaction among systems in the manner of event processing. The event process mechanism referred to information interaction manner of High Level Architecture (HLA) in distributed...
The telegraph training device connect to PC with USB interface helps the telegraph operators to exercise. The core of hardware is STC89C52; After being shaped by pretreatment circuit, the key signal is identified to morse code by adaptive algorithm, and then sent back to the computer. Additional noise superimposed with keying sound is to adjust the training difficulty.
The design based on ARM techniques is to realize a common model of communication equipment simulator. The S3C2410 chip, as the core of hardware, together with FPGA and other interface circuits, realize standardized coding and display controlling; the backstage computer software as a finite-state machine, need to give correct operating response, send display orders, communicate with other simulator...
