Abstract: An interleaving method and apparatus for adaptively determining an interleaving depth of each of one or more interleaving blocks based on a maximum interleaving depth and a number of codewords of a packet, and interleaving the interleaving blocks based on the interleaving depth. The adaptively determining the interleaving depth includes: calculating a number of remaining codewords by performing a modulo operation on a basic interleaving depth and the number of the codewords; and determining the interleaving depth by adjusting the basic interleaving depth based on the number of the remaining codewords.

Abstract: A method and apparatus provide for stable signal demodulation in a communication system. The method and apparatus includes including detecting an erroneous demodulation value based on backward-demodulation of received signals, using a difference between a received signal to be demodulated and a preceding signal of the received signals and correcting the error demodulation value. Alternatively, backward-demodulation is used to confirm received signals.
