BER ANALYSIS OF CHANNEL CODING TECHNIQUES FOR 5G NETWORKS

Everybody since wireless technology serves as the foundation for dependable communication, achieving error-free communication is the main problem. However, because wireless channels are impaired, it is almost impossible to communicate without errors. A channel coding approach is the workable choice for dependable communication with a low error rate. In different wireless communication generations, RS, convolutional codes, turbo codes, and other channel encoding techniques are employed. A new kind of channel coding strategy that prioritizes low complexity and decreased bit error rate is required for the more advanced 5G technologies. The bit error rate and complexity of potential error correction coding techniques for 5G technology are examined in this system. Convolutional and LDPC codes are the two channel coding algorithms that are the primary emphasis of this suggested system. The viability of using LDPC codes with 5G wireless communication is assessed in terms of BER performance and complexity, and it is contrasted with both coded and uncoded convolutional codes. LDPC codes are currently utilized in 4G technologies. According to the results, LDPC codes perform better than other coded systems in terms of BER and complexity. They also help the MIMO-OFDM system reach a channel capacity that is closer to the Shannon limit. It is clear from the research that have been done that LDPC codes perform exceptionally well in terms of BER, making them suitable for use in next-generation wireless communication.
