Design of Polar Turbo Product Codes for Optical Fiber Communications Based on FPGA

We propose a dynamic parameter decoding algorithm for polar turbo product codes (polar-TPC), obtaining performance gains of up to 0.1 dB without additional complexity. Employing field programmable gate array (FPGA) emulations, the performance of polar-TPC at ultra-low bit error rate (BER) is verified. In addition, we construct a 16.7% concatenated polar-TPC and Reed-Solomon (RS) code with a pre-forward-error-correction BER of 2.05×10
