Parallelization of a wcdma system simulator for a shared memory multiprocessor machine

摘要

In this paper a parallelization process of a Wide-band Code Division Multiple Access (WCDMA) system simulator is presented. The WCDMA technique is considered as 3~(rd) generation mobile standard for the air interface. The simulation process demands a great deal of calculation to be completed. The simulation times of the sequential simulator have been far too excessive for interactive use. Therefore, in this paper a parallel approach is presented to speedup the execution times. The achieved results indicate that with the correct use of work balancing algorithms promising results can be achieved. With the use of 4 processors the speedup of 3.1 was achieved. However, the total execution time was reduced to half due to the large sequential part still existing in the simulator.
