“…In [18], LTE-enabled communication system is considered to provide efficient data rate transmission and optimize the amount of throughput over various wireless communications channels such as BSC and AWGN, as the rate-less (LDPC +LT) codes were utilized to represent the fountain code. Still our work merges the rate-less Raptor code with various modulation and data randomizing techniques to achieve superior performance of MIMO-OFDM based system.…”

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.
