Project description
We are designing and evaluating the performance and security of polar codes in a wireless communication system. The system employs physical layer security. It is subject to impulsive noise with different levels of impulsiveness.
To design polar codes optimised for impulsive noise channels, we are using Density Evolution.
The polar codes will have maximal secrecy codes rates when combined with physical layer security. Thus, we can achieve security while minimising the redundancy in the polar codeword.
We are designing an optimal puncturing method to obtain polar codes with arbitrary block lengths. The method can be applied to different modulation schemes, such as:
- binary phase shift keying (BPSK)
- M-ary Quadrature Amplitude Modulation (QAM)
Such schemes can be rate compatible with practical communication systems.
Our results have demonstrated that polar codes are robust to the effects of impulsive noise channel. They can achieve secure communications.
The work also addresses the issue of security on impulsive noise channels. It has provided important insight into scenarios where the main channel between authorised users has varying levels of impulsiveness compared with the eavesdropper’s channel.
