Abstract :
The needs for reliable and flexible downlink communications incorporated with high volume of satellite images in the ground station have inspired the demands for high performance and flexibility computing in the field of Earth remote sensing. Low-density parity-check (LDPC) codes have had a strong impact on achieving reliable communication links. Finding a fast and reconfigurable developing platform for designing high throughput LDPC decoders has become important. In this paper, a graphic processing unit (GPU) platform is proposed to realize this practical implementation. Experimental results show that the proposed GPU-based platform is compatible to serve as a high-throughput LDPC decoder.
