System and method for real time emulation of communication systems

摘要

One inventive aspect relates to an emulation system for real-time simulation of the physical layer of an analog communication system based at least on partly digital computation. The emulation system comprises a digital portion configured to perform digital computations and represent at least part of the signal propagation in the communication system. The system further comprises an analog portion configured to perform analog signal processing and represent other aspects of the physical layer of the communication system. The analog portion provides inputs to and receives outputs from the digital portion. The digital portion is configured to digitally compensate for inaccuracies introduced by the analog portion. Methods of emulating communication systems are also provided.
