The paper is related to an adaptive satellite communication system for data transmission from small, low cost, low Earth orbit satellites. Tests run in a set-up consisting of a number of software-defined radio (SDR) modules operating as a satellite, a ground station, and a satellite channel simulator, have shown that by changing modulation scheme and code rate one can obtain increase of amount of data which can be downloaded from a satellite during a single pass over a ground station approximately by a factor of 2. To determine data rates obtainable in an SDR system using a common personal computer as a digital signal processing device, execution times of particular processing steps involved in the reception process were measured.

“…On the other hand, even state-of-theart PC can occur to be too slow to perform real-time reception of certain kinds of signals. This is why efforts are undertaken to measure execution time of particular operations performed in PC-based SDR systems [1], [2], [3], as well as to optimize some computationally demanding routines [4].…”

“…Alternative microprocessors like Central Processor Unit (CPU) are more flexible than FPGAs/ASICs. Some works on CPUbased software decoding use single-instruction multiple-data (SIMD) instruction sets to achieve parallel decoding [4] [5]. But restricted by their computation resources, the data processing speed and decoding throughputs are much lower.…”

In this paper, we propose a parallel block-based Viterbi decoder (PBVD) on the graphic processing unit (GPU) platform for the decoding of convolutional codes. The decoding procedure is simplified and parallelized, and the characteristic of the trellis is exploited to reduce the metric computation. Based on the compute unified device architecture (CUDA), two kernels with different parallelism are designed to map two decoding phases. Moreover, the optimal design of data structures for several kinds of intermediate information are presented, to improve the efficiency of internal memory transactions. Experimental results demonstrate that the proposed decoder achieves high throughput of 598Mbps on NVIDIA GTX580 and 1802Mbps on GTX980 for the 64-state convolutional code, which are 1.5 times speedup compared to the existing fastest works on GPUs.
