Abstract
A system and method that codes and interleaves data onto separate channels for transmission in a wireless multicarrier system. The multicarrier wireless transmission system has an input terminal for receiving a plurality of user data bits. The system adds error-correcting bits to the user data bits. The system then arranges and stores the combination of error-correcting bits, collectively coded symbols, in a two dimensional matrix. The system arranges the coded symbols by writing them into the matrix according to columns, from left to right. The system then retrieves the symbols from the matrix according to rows, from top to bottom. The system then transmits the retrieved symbols on different carrier frequencies such that consecutive symbols are each transmitted on a different carrier frequency.
