In today’s world, mobile device technologies are advancing with each passing day. People use them to watch videos and deal with important business anywhere. Furthermore, the vigorous development of 3-D streaming technology makes possible the 3-D video conferencing, live broadcast, and online gaming, which made people feel like they were standing right in the scene themselves. However, higher qualities...
Currently SPECT image reconstruction algorithm mainly includes analytical method represented by FBP and iterative method represented by OSEM. The OSEM reconstruction algorithm can obtain better reconstructed image quality, at cost of reconstruction computation time overhead. In order to improve the computational efficiency of OSEM algorithm and to further promote the clinical application of OSEM algorithm,...
In this paper, we propose a fully parallel truncated Viterbi decoder for Software-Defined Radio (SDR) on the Graphics Processing Unit (GPU) platform. We exploit a map-reduce strategy based on the three-point Viterbi decoding algorithm (TVDA) due to the high parallelization potential. The trellis of Viterbi decoding algorithm can be divided into sub-trellises in truncation, which can perform independent...
