“…The decoding of received turbo encoded data is performed by an iterative procedure. Since the performance of turbo codes can be significantly affected by the interleaver, in particular for short frame lengths; several researchers have studied the effect of interleavers on the performance of turbo codes [2][3][4][5][6][7]. However, very few have considered the chaotic interleavers.…”

It is well known that the interleaver plays a critical role in the performance of turbo codes and its design using random and deterministic permutations. In this paper, we present a new method to design a deterministic interleaver with random-like behavior based on two-dimensional chaotic map, so called lozi map. The designed interleaver is called chaotic interleaver. The statistical properties and the performance of such interleaver have been investigated and compared with random interleaver and dithered golden interleaver. Chaotic interleaver results in lowering the latency and the complexity of implementation and enhance the reliability and the security of the communication system.

“…In recent years, there have been some investigations that combine encryption and coding to reduce the complexity of the system. One of these methods is based on adjusting the interleaver or the puncturing mechanism of the Turbo code to enhance reliability and security [10][11][12][13][14][15][16][17][18]. In [10], the authors proposed a joint error correction and encryption approach, but this encryption and coding scheme has a low error-correcting capability and is dependent on the hard decision.…”

“…In this method, chaotic interleaver results in lowering the latency and complexity of implementation and enhances the reliability and security of the communication systems. The authors in [17] found that the processing time is significantly reduced compared with the normal block interleaver at the same time while preserving the BER in an allowable range by using sub-interleavers. In other approaches proposed in [13,18], the performances are slightly decreased when the interleaver is controlled.…”

Multiple‐Input Multiple‐Output Orthogonal Frequency Division Multiplexing (MIMO‐OFDM) is an essential technology in the wireless communication system. However, its performance is significantly affected by Carrier Frequency Offset (CFO), which leads to inter‐carrier interference (ICI). The CFO estimation and compensation techniques are used to mitigate the Doppler effect. In addition, the confidentiality of data is a key factor of the system. This paper proposes a Turbo‐based encryption and coding scheme to improve reliability and security for the MIMO‐OFDM wireless communication systems affected by the Doppler frequency offset. In our proposed scheme, the secret key is produced from channel parameters between legitimate users and it is used as a seed for generating a pseudo‐random bit sequence using an Advanced Encryption Standard (AES) generator with variable key lengths. The Turbo code's puncturing mechanism is controlled by this pseudo‐random bit sequence. The proposed method is applied to the system with different modulation schemes through the Rayleigh channel. The simulation results show that the system affected by the Doppler effect would obtain the best performance when using the highest key length of the AES generator, the BPSK, and a great number of receive antennas. Furthermore, the proposed solution outperforms several previous approaches for the MIMO‐OFDM systems.

Turbo coding is a very powerful error correction technique that has made a tremendous impact on channel coding in the past two decades. It outperforms most known coding schemes by achieving near Shannon limit error correction using simple component codes and large interleavers. This paper investigates the turbo coder in detail. It presents a design and a working model of the error correction technique using Simulink, a companion softwareto MATLAB. Finally, graphical and tabular results are presented to show that the designed turbo coder works as expected.
