Abstract:
|
In this paper, we propose a novel opportunistic
decoding scheme for network coding decoder which significantly
reduces the decoder complexity and increases the throughput.
Network coding was proposed to improve the network
throughput and reliability, especially for multicast transmissions.
Although network coding increases the network performance,
the complexity of the network coding decoder algorithm is still
high, especially for higher dimensional finite fields or larger
network codes. Different software and hardware approaches were
proposed to accelerate the decoding algorithm, but the decoder
remains to be the bottleneck for high speed data transmission.
We propose a novel decoding scheme which exploits the structure
of the network coding matrix to reduce the network decoder
complexity and improve throughput. We also implemented the
proposed scheme on Virtex 7 FPGA and compared our implementation
to the widely used Gaussian elimination. |
