Abstract

This paper presents the GPU based software DVB-T receiver design. We first propose the software DVB-T receiver using just one CPU core and investigate the gap between the required time budget and the actual simulation time. Based on the simulation results we partition the algorithm such that some of the algorithm corresponding to the critical path can be processed by the GPU which adopts massively parallel processing elements. To increase the thread usage we design software algorithms which reduce the FFT and Viterbi decoding processing time by the ratio of 10~20 times compared with the CPU based processing.
