Reliable wireless communication needs a highly efficient Forward Error Correction (FEC) technique in order to counter the effects of noise, interference, and losses. Most existing FEC techniques add too much redundancy and create extra latency, thereby reducing the efficiency of bandwidth utilization. Hence, the purpose of the current research is to design a new model, called Adaptive Convolution-Assisted Polar Encoder with Flexible Iterative Decoding (ACAPE-FID). This hybrid FEC method uses a combination of Adaptive Frozen Polar Coding, Convolutional Encoding, and Flexible Iterative Decoding using Reed-Solomon Euclidean. ACAPE-FID adapts the number of frozen bits based on the number of input bits, so there is no unnecessary redundancy in the system, and it uses sequential Turbo-based iterative decoding to achieve correct error correction in case of congestion in channels. The developed algorithm was designed and implemented using MATLAB HDL Coder on Xilinx Zynq-7000 FPGA, and its performance evaluation was conducted to show that ACAPE-FID had superior results in terms of BER=10-9, BLER=10-7, FER=0.001, latency=0.01 μs, loss=1%, efficiency=0.94%, SNR=3.1 dB, PSNR=33, and throughput=12 Mb/s compared to traditional Polar, LDPC, TBCC, and Turbo coding schemes.
