“…Decoding is done the same way as described in this paper for LT decoding. LDPC decoding is performed using the BP algorithm [25]. From the previous prelude, it can be concluded that the computational complexity of Raptor code equals O (Symbol size) for generating the encoded symbol from the source block.…”

Due to the importance of both rate-less digital fountain codes and Multi-Input Multi-Output (MIMO) schemes in Fifth and Sixth Generation (5G/6G) wireless networks, this paper investigates enhancing the performance of MIMO-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) based system by employing the rate-less fountain codes. The rate-less codes, such as the Tornado codes and Raptor codes, have a flexible code rate that differs from the classical channel coding schemes. This paper uses Raptor code to study the MIMO system's performance with the rate-less codes over different wireless communications channels. The proposed MIMO-fountain code-based system has been tested over the various wireless communication channel conditions concerning the varied Frequency Doppler (FD). In the proposed rate-less wireless communication system, multiple interleaving techniques and equalizers are used to improve its performance. Computer-based simulation experiments are assigned to evaluate the MIMO-fountain code system using the different data transmission scenarios. Simulation results confirm the superiority of the presented wireless rate-less system compared to fixed-rate wireless systems in terms of Bit Error Rate (BER) and throughput.

This work contributes to the multimedia security fields by given that more protected steganography technique which ensures message confidentiality and integrity. An Advanced Least Significant Bit (ALSB) technique is presented in order to meet audio steganography requirements, which are imperceptibility, capacity, and robustness. An extensive evaluation study was conducted measuring the performance of proposed NLSB algorithm. A set of factors were measured and used during evaluation, this includes; Peak Signal to Noise Ratio (PSNR) and Bit Error Rate. MP3 Audio files from five different audio generators were used during evaluation. Results indicated that ALSB outperforms standard Least Significant Bit (SLSB) technique. Moreover, ALSB can be embedding an utmost of 750 kb into MP3 file size less than 2 MB with 30db average achieving enhanced capacity capability.

Due to the power efficiency importance of digital signal processing and data protection in different communications systems, this paper proposes an efficient design of different Hamming Codes utilizing Full Swing- Gate Diffusion Input (FS-GDI) approach. The proposed codes design aims to improve the power efficiency and the required area through reducing the required number of transistors. FS-GDI is a new low power VLSI design approach, it is a power effective approach for realizing the different logic gates. In this work, the Hamming codes (7, 4) and (11, 7) are designed by utilizing the original GDI, FS-GDI and the traditional CMOS approaches. The amount of consumed power, delay time, Power Delay Product (PDP) and hardware simplicity-Number of Transistors (No.Ts) are employed as a metrics for evaluating the efficiency of the proposed design compared to the traditional design. The design simulation experiments are executed utilizing Cadence Virtuoso simulator package under 65nm technology. The simulation experiments revealed these proposed codes achieve delay time reduction by 52.91% and 10% for Hamming codes (7, 4) and (11, 7), respectively On the other hand, the Hardware (H/W) of these codes became more simple where the H/W simplicity of the used Hamming codes is reduced 50 % CMOS approaches respectively. From the results analysis, the proposed design achieves efficient power and the delay optimizing of Hamming codes utilizing the FS-GDI approach. On the other hand, the power consumption and area in communications systems due to the encoding process can be reduces.
