Bit switching decoding of Cyclic Hamming codes for IoT applications

Being a requirement of low power transmission for IoT, it requires a decoder offering a good performance. URLLC (Ultra-Reliable Low Latency Communication) had the requirement of Ultra reliability, and Ultra-low latency hence demands a low complexity yet a good performing decoder. The use of hard decision decoding for Block codes over fading channels leads to performance loss. Soft decision decoding gives a good performance, but it is computationally costly. This paper proposes a diversity preserving hard decision decoding scheme for Hamming codes, offering a good performance. The complexity of the proposed decoding technique is of the order of $n$ (codeword length) and is very suitable for IoT and URLLC applications.
