Hamming code transceiver is used to make communication possible in full duplex mode in place of simplex mode by even parity and odd parity check method. Here transmitter and receiver replaced by transceiver in transmitter and receiver section. 31 bit Hamming code transceiver generate 31 bit data string for 25 bit information data and regenerate 25 bit information data from received 31 bit corrupted data string at both source and destination section. Till now communication is possible only for 7 bit information data string, now after using this technique communication is possible for 25 bit information data string. Это и многое другое вы найдете в книге Communication by 31 bit Hamming Code Transceiver (Brajesh Kumar Gupta and Rajeshwar Lal Dua)
