“…In the literature, several improvements to the original OSD algorithm have been presented that aim to reduce the complexity of the optimal decoder and offer a finer performancecomplexity trade-off [13]- [19]. In our implementation of the algorithm we used the probabilistic necessary condition from [17], the probabilistic sufficient condition [15], the reference re-encoding scheme [17], the preprocessing rules from [16], and the multiple biases diversity scheme from [18].…”

Abstract-We compare the performance of short-length linear binary codes on the binary erasure channel and the binaryinput Gaussian channel. We use a universal decoder that can decode any linear binary block code: Gaussian-elimination based Maximum-Likelihood decoder on the erasure channel and probabilistic Ordered Statistics Decoder on the Gaussian channel. As such we compare codes and not decoders. The word error rate versus the channel parameter is found for LDPC, Reed-Muller, Polar, and BCH codes at length 256 bits. BCH codes outperform other codes in absence of cyclic redundancy check. Under joint decoding, the concatenation of a cyclic redundancy check makes all codes perform very close to optimal lower bounds.

“…Therefore, we can consider the performance achieved by Eve through iterative decoding as a reliable estimate of the optimal decoder performance. This also avoids the need to consider that Eve uses other decoders, like, for example, those based on ordered statistics decoding (OSD) algorithms [25], which exploit the concept of information set decoding (ISD) [26], aided by the soft information available at the channel output. An algorithm similar to ISD was also proposed in [27] to attack two authentication protocols which exploit some noisy observations.…”

Abstract-The broadcast channel with confidential messages is a well studied scenario from the theoretical standpoint, but there is still lack of practical schemes able to achieve some fixed level of reliability and security over such a channel. In this paper, we consider a quasi-static fading channel in which both public and private messages must be sent from the transmitter to the receivers, and we aim at designing suitable coding and modulation schemes to achieve such a target. For this purpose, we adopt the error rate as a metric, by considering that reliability (security) is achieved when a sufficiently low (high) error rate is experienced at the receiving side. We show that some conditions exist on the system feasibility, and that some outage probability must be tolerated to cope with the fading nature of the channel. The proposed solution exploits low-density parity-check codes with unequal error protection, which are able to guarantee two different levels of protection against noise for the public and the private information, in conjunction with different modulation schemes for the public and the private message bits.Index Terms-Broadcast channel with confidential messages, low-density parity-check codes, physical layer security, quasistatic fading channel, unequal error protection.

“…Several options are available for this purpose, also exploiting LDPC-like code representations [14]. For this code, we have focused on the MRB algorithm [15], which has very good performance and acceptable complexity. It consists of the following steps: 1) Identify k = 64 most reliable received bits and obtain from them a vector v * .…”

“…6) For each of them: sum to v * , encode by G * , verify if the likelihood is higher than that of the previous candidate codeword and, if this is true, update the candidate. Further details can be found in [15] and the references therein. The MRB algorithm can be applied also to the other schemes (to LDPC codes, in particular) where, depending on the order i, it can provide performance comparable to, or even better than, that offered by the iterative algorithms.…”

The aim of this paper is to study the performance of some coding schemes recently proposed for updating the TC channel coding standard for space applications, in the presence of jamming. Besides low-density parity-check codes, that appear as the most eligible candidates, we also consider other solutions based on parallel turbo codes and extended BCH codes. We show that all these schemes offer very good performance, which approaches the theoretical limits achievable.
