“…Secondly, noted that the subsequent channelization and spectral analysis processing cannot distinguish the timedomain information of the signal, it is necessary to mark the time-domain information of the signal while identifying the channel. In this section, we use time-frequency analysis combined with image edge detection to identify the channel of the signal effectively [30]- [33]. As a chaotic multi-tone modulation signal, each single tone can be regarded as a result of time and frequency shift.…”

With the development of communication countermeasure technology, the existing communication mode is exposed to intercept or decipher in the covert transmission of information. Therefore, the development of a new concept and principle covert communication technology with low interception probability and anti-non-cooperative demodulation has drawn increasing attention. In this treatise, we propose a chaotic multi-tone modulation and demodulation technology thus present a method to construct the covert communication system. The technology constructs chaotic multi-tone sets to express the baseband information with the multi-value mapping based on the dynamics principle, which can express the same baseband information with different multi-tone groups. Signal modulation is accomplished by combining frequency hopping and baseband information scrambling technology. Multi-value mapping is adopted to complete chaotic multi-tone modulation. Specifically it has strong information concealment and anti-noncooperative demodulation characteristics. In order to solve the demodulation problem of the cooperative party, we present a demodulation scheme based on chaotic multi-tone and provide a complete chaotic multitone communication system construction scheme. Simulation results verify the performance of the proposed method. INDEX TERMS Chaotic multi-tone, covert communication, low interception probability, information concealment.

“…In noisy channels, using error correction code (ECC) is considered an important for digital communication systems to achieve the reliability of the transmission information [22]. In practical applications, Bose-Chaudhuri-Hocquenghem (BCH) is usually adopted to achieve data reliability among the several ECCs because of its acceptable hardware cost and strong error correcting performance [23].…”

<span>Due to its large peak to average power ratio (PAPR) and high out of band emission (OOBE), OFDM doesn't meet the requirements of 5G services. Additionally, it supports only one type of waveform parameters in entire bandwidth. In contrast, f-OFDM is dividing the system's bandwidth into a number of subbands to support several waveform parameters based on various service scenarios. So, Filtered-OFDM (f-OFDM) is considered as a modern enabler of the flexible waveform to overcome the OFDM drawbacks while remaining its advantages as well as, to encounter the new challenges that faced 5G. Nonetheless, there is a trade-off among OOBE, PAPR and SNR performance. Meanwhile, channel coding technology is one of the most important issue in physical layer which is playing an essential role in order to achieve the reliability and latency. So, BCH code has been suggested in this paper for f-OFDM system to achieve the reliability of transmission information and thus improving BER performance over multipath fading channel. Whilst, BCH-LTE system is introduced as a baseline in this paper that using for comparison purpose with proposed system. Simulation results showed that the proposed BCH-f-OFDM system was significantly better than BCH-LTE system in terms of decreasing OOBE and achieving improving in BER performance. Although, PAPR levels was stilling high in proposed system due to the trade-off among OOBE, PAPR and SNR performance. However, the proposed system is considered a promising candidate to meet the requirements of 5G services because of its ability to solve two important issues in between three trade-offs'.</span>

“…So, applying powerful FEC techniques are considered one of the key method to improve the BER performance and receiver sensitivity [14]. So, to achieve the reliability of information transmission in digital communication systems over noisy channels, ECC is considered an essential issue [15]. Where, several ECC have been suggested in 4G such as turbo, LDPC, convolutional, BCH and RS codes [16][17][18][19][20] and in 5G such as LDPC, turbo, polar and convolutional [21] and BCH [22].…”

Fifth generation (5G) mobile communication is expected to be deployed in several countries by 2020. Where, the data consumptions are expected to be increased to 30% thus, it cannot be supported by the present technologies 3G and 4G. In contrast, looking for new alternative modulation techniques of orthogonal frequency division modulation (OFDM) system which is suffering from high peak to average power ratio (PAPR) and out of band (OOB) side lobes are needed to use in 5G communication system. Hence, universal filtered multi-carrier (UFMC) is considered as alternative waveform to overcome of OFDM disadvantages. In communication systems, channel coding is considered vital part, where error correction codes (ECC) are used to detect and correct the errors which is occurring in channel noise. In this paper, RS codes are suggested with UFMC system to achieve the reliability of information transmission over noisy channels. The results showed that although, the values of PAPR levels for using RS codes in UFMC increased to 8.8653dB against 6.9735 dB for OFDM system. However, there are significant improvements in BER performance owing to use RS codes against uncoded-UFMC system. Furthermore, the values of OOB in UFMC system was lower than OFDM system.
