A method for performing 3/5 major voting in the TACS/AMPS mobile phone system, in which a word of the message frame is transmitted repeated five times and every bit of the word is given a value at reception by major voting of the five repeats. The number of ones or zeros of a bit C is counted at least to three. This number is saved as a binary two-bit number B&prime;A&prime; in two memories ( ) so that the first ( ) contains the least significant bit A&prime; of the number B&prime;A&prime; and the second ( ) contains the most significant bit B&prime; of the number B&prime;A&prime;. After the fifth repeat of the bit C, the final number of ones or zeros of the bit C has been counted and saved in the memories ( ) and voting is performed on the bit C based on bits A&prime; and B&prime; indicating the number of ones or zeros.
