Using Polar Codes for Low Overhead Error Correction Encoding in Underwater Acoustics
Abstract
Polar coding is a linear block coding method notable for its channel capacity-achieving performance with low-complexity encoding and decoding algorithms. Polar codes are ideal within a presumed channel description, here an additive white Gaussian noise (AWGN) was assumed. This paper will demonstrate the application of polar codes to reduce bit errors for underwater acoustic communications by applying them to frequency shift keying (FSK) modulation. Compared with traditional rate-1/2 convolutional error correction encoding, polar was shown to have lower probability of bit error and had less overhead another critical concern for very short transmission frames.
