Abstract: The fifth generation (5G) wireless networks utilize small cell deployments to satisfy the growing need for high data rates, ultra-reliable communications, and low-latency services. Dense small cell environments bring along challenging conditions such as high interference, elevated mobility, and fluctuating channel conditions, which compromise the reliability of the transmission. Forward Error Correction (FEC) methods, specifically Low-Density Parity-Check (LDPC) codes and Polar codes, are crucial to combating transmission errors without the need for retransmissions. In this paper, an adaptive FEC control mechanism designed for 5G small cell networks is introduced. The system dynamically varies coding rates and block lengths according to real-time channel feedback, maximizing the trade-off between throughput, latency, and error correction ability. Extensive simulation outcomes illustrate that adaptive FEC performs well above conventional static coding techniques, improving link reliability, lowering latency, and sustaining quality of service (QoS) under fluctuating network scenarios. This mechanism aids in creating robust and effective next-generation wireless systems.
