摘要： Provided are an interleaving apparatus and method in a communication system. The interleaving apparatus includes a determiner for determining whether a next index k to be generated is an index to be discarded, and if the next index k is the index to be discarded, generating a skip signal; an index generator responding to a clock to increase the next index k by “1” and output the increased index k, and if the skip signal is detected, increasing the index k by “2” and outputting the increased index k; and an address generator performing a predetermined operation using the index k generated by the index generator to generate an address required for interleaving. Thus, a number of clocks required for interleaving and/or deinterleaving can be reduced.
