  Channel polarization and Polar code are widely considered as major
breakthroughs in coding theory because they have shown promising features for
future wireless standards. The main drawbacks of Polar code are high-latency in
decoding hardware, and unimpressive error-correction performance in case
limited code-length is implemented. These two disadvantages limit
implementation of Polar code in low-throughput wireless communication systems.
In this paper, we propose a low-complexity low-latency hardware architecture
for the soft-decision compact (16,11) Systematic Successive Cancellation Polar
Decoder (S-SCD). Experimental results has shown that the latency of the
proposed S-SCD improves 3.75 times and 2.75 times compared with conventional
and 2b-SC architectures. Besides, it has also shown a better BER/FER
performance compared with RS(15,11) code, which is applied widely in current
VLC-based systems.
