Patent ID: 7035408

Claim:
A method to generate a pseudo-random sequence of multi-carrier data symbols, said method comprising: producing a pseudo-random bit sequence by repetitively generating a pseudo-random sequence of L bits, L being a first integer value; packetizing into multi-carrier data symbols thereby using N bits of said pseudo-random bit sequence per multi-carrier data symbol, N being a second integer number, to thereby generate said pseudo-random sequence of multi-carrier data symbols, wherein said packetizing comprises: dividing said pseudo-random bit sequence into strings of N′ bits, N′ being a third integer value larger than N, wherein N is greater than or equal to two, N′ differs from L−1 and from L+1, and N′ is not fractionally related to L; and using N bits out of each string of N′ bits to generate a multi-carrier data symbol out of said pseudo-random sequence of multi-carrier data symbols, and leaving N′-N bits out of each string of N′ bits unused.
