To ensure the security and reliability of data traffic generated from wireless sources, 5G networks must be designed to support security protocols and reliable communication applications. The operations of coding and processing of information during the transmission of both binary and non-binary data in nonstandard communication channels are described. A subclass of linear binary codes is considered, which are both Varshamov-Tenengolz codes and are used for channels with insertions and deletions of symbols. The use of these codes is compared with Hidden Markov Model (HMM)-based systems for detecting intrusions in networks using flow watermarking, which provide high true positive rate in both cases. The principles of using Bose-Chadhuri-Hocquenhgem (BCH) codes, non-binary Reed-Solomon codes, and turbo codes, as well as concatenated code structures to ensure noise immunity when reproducing information in Helper-Data Systems are considered. Examples of biometric systems organization based on the use of these codes, operating on the basis of the Fuzzy Commitment Scheme (FCS) and providing FRR < 1% for authentication, are given.

Simulation results demonstrating the efficiency of turbo codes used to improve the noise immunity of BPSK and 8PSK data transmission over the AWGN channel are presented.

Statistical and computational experiments demonstrate that proposed scheme outperforms the known coded IPD-based flow watermarking schemes and has a significant advantage in detection rate and implementation complexity, but slightly inferior to the code rate, and hence to processing time for intrusion tracing.

Two schemes for block-based transmission of variable-length codes

Two schemes of block composition are examined: the use of zero bits padding and appended marker code (first scheme) and then padding bits only (second scheme). It is observed that the error span is limited in both schemes but the second scheme with reduced overhead performs better when the sequential decoding of VLC is exploited.

The results obtained show that error performance may be improved only by exploiting the resynchronization technique, without the use of forward error control coding.

The numerical analysis of the extended multi-pulse position modulation (MPPM) and CPPM for information transmission done in aspects of bandwidth, power efficiency and symbol error probability (SER) has shown the better performance of CPPM and MPPM than SPPM at the cost of increased bandwidth. The obtained simulation results of SER for modulation schemes are close to theoretical SER evaluation and have shown the increase of power spectral density (PSD) of MPPM in comparison with SPPM.

The evaluation of scheme demonstrates similar to known scheme performance but with lower complexity as soon as its implementation is mainly based on linear decoding operations.

Such codes may be used not only when the source statistics is known but also when we do not know the source probability distribution, and a source with equal symbol probabilities (equiprobable symbols) can or has to be assumed. This paper presents variable-length codes with code words that differ in length by at most one code symbol. Such codes suit the efficient encoding of sources with equiprobable symbols. We accommodate non-binary codes and present an iterative algorithm for the construction of such codes. We also calculate the average codeword length for such codes, which extends Krichevski's result for binary codes [5]. Finally, we propose a scheme that allows the code to be communicated efficiently from transmitter to receiver.
