“Scientists of Peter the Great St.Petersburg Polytechnic University (SPbPU) proposed a new channel coding method for the fifth generation of wireless systems (5G). Channel coding theory studies techniques for introducing redundancy into information, to protect it from errors that occur during transmission or storage. For example, human speech has some redundancy, so that not every combination of sounds or letters is a permissible word. This enables people to communicate even in a noisy environment. Storage and information transmission systems are integral parts of gadgets, smartphones and computers. Their developers must implement simple and reliable methods to protect data from corruption. Currently, many universities in the world are working on improving polar codes. This is the method of noise-immune coding developed by Turkish scientist Erdal Arikan. Significant progress in this area was achieved by SPbPU.”
