This study investigates FEC methods devised for underwater communication systems that experience severe environmental conditions. We set up a model of an underwater acoustic communication channel by incorporating the essential parameters: Attenuation, Absorption, Doppler shift, Noise interference, Complex propagation environments, and Multipath propagation. From the set of FEC schemes studied, the Polar FEC scheme was superior in performance and is therefore the best option for underwater communication. Performance tests are carried out with modulation techniques through BPSK and QPSK with varying parameters on the number of trials and code length with results evident on the adaptability and efficiency of Polar FEC to improve reliability in underwater acoustic communication.
