Real-time Software GNSS Signal Simulator Accelerated by CUDA
Software GNSS signal simulators produce the digital IF signal to test the algorithms of GNSS receiver. Because of the limitation of parallel computing capability that general CPU can provide, software GNSS simulator cannot generate signal synchronously when the sample rate is tens of MSPS. To solve this problem, a DDFS algorithm accelerated by CUDA technology is introduced. By optimizing the data transitions and execution path, the real-time simulation can run at sample rate up to 58MSPS. The simulator has been proved functional by general GNSS acquisition and tracking software.
