Abstract:
1. An apparatus for generating an error detection information sequence for determining a length of data sequence transmitted, in a communication system which can transmit at least two data sequences with different lengths through a data channel, and transmit through a data control channel a control data sequence for each of the at least two data sequences, each of the control data sequences having a same length as the at least two data sequences, respectively, and including a control information sequence indicating information with regard to each of the at least two data sequences and an error detection information sequence for detecting an error of the control information sequence, the apparatus comprising: a plurality of cascaded registers, the number of the registers being equivalent to the number of bits in the error detection information sequence; a plurality of adders determined by a predetermined generator polynomial positioned between the registers, each of the adders adding a bit sequence received through an input path to a feedback bit sequence and outputting the addition result through an output path; an operator that,
