THE PROPOSED SOLUTION OF THE DECODER CHANNELS FOR PRODUCT CODES

Abstract

Industrial wireless sensor network requires strong channel codes with communication with short packages. Product codes are a family of channel codes which only require short codeword to achieve very good errror correction thanks to the minimum hamming distance. Due to the complex decoding process, product codes haven’t yet been proprosed for application in communication systems. With the desire to exploit the error control ability of product codes in modern communication applications, this article which bases on the theory of product codes decoding and selects Hamming codes as component codes proposes interative decoding algorithms which is appropriately applied to the product codes with good decoding performance and acceptable complexity. Simulation results have shown that at the bit error rate (BER) of 10-5, the requirement of signal to noise ratio is only 3,7 dB in case of using Hamming codes (31, 26) as the component codes.
