“…As described in Fig. (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) below at (a), (b), and (c), a basic square matrix of 8x8 equals 64 items (c). The designer must select a key that satisfies the chaotic interleaver condition, which divides the square matrix into N-element rectangles.…”

“…The ability to tolerate burst errors is improved by bit interleaving, which can break the inherent correlation in the input bit sequence through specific permutation rules and intelligently reorder the original bit sequence [5]. The design of Forward Error Correction (FEC) codes like the Turbo code [6] [7] and LDPC code frequently employs bit interleaving. For turbo codes, an interleaver is used between the two component encoders.…”

Communication and computing systems have made it easier for the world to transfer data and information from the sender to the recipient at the lowest cost and most efficiency. The transmission process may cause data corruption or error for many reasons, including the environment, the large volume of transmitted data, heat, and noise. for these Reasons, There is a need to correct and treat these errors. Individual errors can be easily corrected by hamming code, while burst errors cannot be corrected easily and need a hardware device called the interleaver used to correct the burst error. In this research, the different types of interleaver are studied and compared to find the best interleaver in order to increase the efficiency and accuracy of the systems. The issue is that interleaving takes a long time, which increases the turbo code's overall execution time. Our goal is to create an interleaver that is more sensitive and efficient than other varieties. Index Terms— interleaving, Chaotic Interleaver, turbo codes, 2d baker map.

“…Bit interleaving can break the inherent correlation in the input bit sequence through certain permutation rules, and the original bit sequence is wisely reordered, enhancing the ability to resist burst errors [2]. Bit interleaving is widely used in the design of Forward Error Correction (FEC) codes such as Turbo code [3] and LDPC code. There are many bit interleavers studied in the literature.…”

In order to combat the impulse noise and channel time-frequency selective fading, it is essential to use channel interleavers. Among them, the block interleaver has been widely used in terrestrial broadcasting systems such as DVB-T2 and ATSC 3.0, since it can better reflect the mapping relationship of data units on time-frequency resources. Due to the limited value of the interleaving structure parameter, the existing block interleavers cannot fully exploit time and frequency diversities, which leads to a loss of partial diversity gains. To address this problem, this paper proposes a generic block interleaver for channel interleaving through jointly considering the time and frequency diversities. First, row crossing is performed according to a certain interval, which will increase the interleaving distance; then, cyclic shift is used to achieve a greater time diversity gain. The proposed method can achieve flexible parameter configuration, which can effectively increase the scalability of the parameters and make the interleaver more versatile. Theoretical analysis shows that a larger interleaving distance is obtained and the multiplicity of minimum distance is significantly reduced. The simulation results of the fixed and mobile reception scenarios in the terrestrial broadcasting systems demonstrate the effectiveness of proposed interleaver compared to existing block interleavers.
