The Sora platform, which is a fully programmable, high-performance software radio platform based on a commodity general purpose PC, has recently received significant attention. However, acceleration techniques used in Sora are too complicated for developers, which can prevent researchers from modifying physical layer (PHY) processing. This paper presents the CuSora platform, which integrates the Sora...
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...
