Accelerating the Spatial Channel Model Enhanced(SCME) Using NVidia CUDA in 3GPP LTE-Advanced System Level Simulation

With the rapid development of the 4th wireless communication systems, new algorithms and innovations makes the evaluation and simulation tools become more and more important. But in fact, the more detail and real the model is, the more time and resources are reqiured, that is, much time is required to perform simulation, which is unacceptable for large amount of simulation work. In this work, we concentrate the widely used channel model raised by 3GPP. Time and resource consumption of the Spatial Channel Model Enhanced (SCME) used in 3GPP LTE physical layer system level simulation is the big problem. In this paper, we accelerate the SCME using NVidia CUDA, which is the extension of our previous work. Simulation result shows that our novel method works 37 times faster than original method, which is an amazing and exciting result.
