Patent ID: 7028230

Claim:
A method for filling a matrix ( 51 ) used in interleaving a packet of bits for transmission as symbols via a wireless communication channel, the transmission using a modulation scheme in which a number n b/s of bits are encoded per symbol, the matrix having a fixed number n 1 of elements in a first dimension and a variable number n 2 of elements in a second dimension, the method including sizing the matrix so as to accommodate the number n p of bits in the packet given the number n 1 of elements in the first dimension of the matrix, the first dimension being either a row or a column depending on whether the interleaving provides bits for modulation column-wise or row-wise, respectively, the method characterized in that it includes a step ( 72 ) in which the number n 2 is adjusted to a number n 2 ′ that is not divisible by the number n b/s of bits per symbol, thereby providing a matrix that cannot be exactly filled by a packet of bits.
