“…< R M , where mode "0" corresponds to no data transmission or outage. In this article, proper codes are those in their performance curve, a little change in SNR results in a great change in BER, accurately those with a low security gap (Klinc, Ha, McLaughlin, Barros, & Kwak, 2009). In Figure 2, security gap is shown; through a decrease of received SNR by the security gap d, BER decrease from proper level to improper level.…”

A new transmission scheme is presented for a two-hop relay network including two AF relays, considering physical layer security where relays are not able to detect signal with an acceptable bit error rate (BER) but the combined received signal is detected with an acceptable BER at the final receiver. It is assumed that there is no direct path between the transmitter and the receiver (relay network without diversity). Adaptive modulation and coding is utilised at the transmitter and transmission powers of the transmitter and of the relays are continuously adapted provisioning individual average power constraint for each node. Numerical evaluations show that an acceptable performance degradation is seen by the proposed secure relaying scheme compared to the optimum relay selection scheme without security constraint.

“…Nevertheless, medium or short length LDPC codes have also their applications. In [3] Klinc et al propose a coding scheme for the Gaussian wiretap channel based on LDPC codes (codeword length n = 2364 with code rate R = 2/3). Bit error rate -BER is used as a measure for security in this paper.…”

LDPC codes have been intensively used in various wireless communication applications, due to their increased BER performance. The present paper summarizes the state of the art applications of short length LDPC codes and proposes FPGA based application specific hardware architectures for shortlength LDPC decoders. The decoding algorithms considered for implementation are both belief propagation and min-sum algorithm. Due to the increased BER performances, the proposed architecture make use of parallel computation capabilities offered by FPGA technology in order to implement the belief propagation algorithm. In spite of the iterative nature and increased computational complexity of the LDPC decoding algorithm, the proposed architecture achieves high-throughput, mandatory in real-time application and data transmission. The architecture for the LDPC belief propagation based decoder is based on arctangent hyperbolic function approximation used for check nodes update.

“…In the paper above, only theoretical derivation on the performance of coset coding was made, the implement method in detail was not underway yet. In [8][9], Klinc, Andersson and et al added randomness to increase the uncertainty of the eavesdropper. However, these methods decreased the reliability of the legitimate receiver in reverse.…”

Abstract-Coset coding is a typical method of secure coding in physical layer security. This paper focuses on coset coding based on the random linear codes in binary symmetric channel. While analyzing system security, we derive the formula of eavesdropper's equivocation and proposed a novel code extending algorithm based on the optimization of minimum distance. On the basis of ensuring minimum distance of the code reaching the maximum, the algorithm searches the achievable extended column to ensure the equivocation of eavesdropper up to the most as well. The simulations show, compared with the best known code (BKC) and best equivocation code (BEC) of the same code length and rate, the proposed algorithm has better security and higher efficiency.
