With advancements and new proposals in wireless communication standards, there is an increase in the demand for band-width-efficient wireless transmission mechanisms. The 5G networks will also enable the Internet of Things (IoT) by creating more efficient and reliable networks for billions of connected devices. Error-Correction Coding (ECC) is a powerful technique to ensure reliable and secure communication in wireless multimedia systems. ECCs are essential for modern wireless communication as they help reduce the amount of data lost during transmission due to errors and noise in the channel. Recent research has demonstrated the usefulness of Low-Density Parity-Check (LDPC) codes for 5G and beyond communication. This paper compares LDPC with polar, Reed-Muller, and convolutional codes, along with a motivation for their application in wireless multimedia communication. Simulation results show that the LDPC outperforms Reed-Muller, polar, and convolutional codes for larger block length codes. Thus, two sub-classes of LDPC codes, AR4JA and AR3A, with different decoding algorithms, are presented for possible adoption in next-generation reliable communication. The performance is evaluated in terms of the Bit Error Rate (BER) and code rate. The paper also highlights the importance of using ECCs in wireless multimedia communication to improve data transmission reliability and reduce channel impairments' impact. More specifically, the AR4JA exceeds the AR3A by a factor of 0.5 dB SNR at the BER degradation point of 10-8 and attains the error floor level of 10-9.

Keywords: 5G LDPC, Error-Correction Coding (ECC), the Bit Error Rate (BER)
