چکیده

JNCC seamlessly couples channel coding and network coding to effectively combat the detrimental effect of fading of wireless channels. In this paper we used Joint Network-Channel Coding scheme, for reliable multiple access relay channel. Specifically, JNCC combines irregular lowdensity parity-check (LDPC) channel coding and random linear network coding through iterative joint decoding, which helps to fully exploit the spatial diversity and redundancy residing in both channel codes and network code through this we have analyse BER,GER,FER,PER in order to achieve diversity gain. The simulation results show that JNCC provides selection gain compared to the direct Transmission. Analytical and simulation results are presented to evaluate the performance of this system. Keywords—JNCC, LDPC Codes

An efficient secure channel coding scheme based on polar codes

In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...
