Title:
COMMUNICATION METHOD, MULTIPATH REDUCING METHOD, AND RECEIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/083502
Kind Code:
A1
Abstract:
Provided is a communication method comprising a first frequency conversion
step of DFT-converting the input signal of an N-chip signal received through
a communication line having multipath characteristics, to determine a matrix
(e0, e1, - - -, eN-1)t of an N-th order,
a second frequency conversion step of DFT-converting the N-chip signal of a period
(N) matching the multipath characteristics, to determined a matrix (d0,
d1, - - -, and dN-1)t of the N-th order, an orthogonalization
step of determining Expression (1) from a matrix vector (d0, d1,
- - -, and dN-1): [Numerical Expression 14] - - - (1) and an orthogonal
matrix multiplexing step of multiplexing the matrix (d0, d1,
- - -, and dN-1)t by the diagonal matrix of Expression (1).
