Abstract
An error-trapping decoder is provided that performs right cyclic shifts of a received shortened codeword in a decode shift register. Consequently, the error burst portion of the received codeword is encountered in the register within the length of the shortened code. In other words, the number of right cyclic shifts required by the shift register to encounter the error burst portion of the received word is on the order of the length of the shortened word.
