IPC: H04J13/00
Filed: 2001-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a system that generates a training sequence to execute training of a receiver by using a least mean square(LMS) algorithm having a short wait time. SOLUTION: The orthogonal sequence is expanded for a channel of a finite impulse response(FIR) filter with a length Mnew from an existing orthogonal training sequence with respect to at least two channels having lengths Mold1, Mold2 shorter than the lengths Mold1 and Mold2 so that the product of the Mold1 and Mold2 is equal to the Mnew when the lengths Mold1 and Mold2 has no common prime number factor. In the case of a channel whose length is M, the orthogonal training sequence with the length Mold1 and Mold2 is expanded by repeating the training sequence oil 1 by number of Mold2 times and repeating the training sequence old 2 by number of Mold1 times when sets of the orthogonal training sequence having an initial value are found out as to known symbol sets.
