Title:
MULTI-CARRIER CODE DIVIDING MULTIPLEX TRANSFER SYSTEM AND METHOD, AND RECEIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/037320
Kind Code:
A1
Abstract:
A multi-carrier code dividing multiplex transfer system comprises a direct demodulator
(12) for deciding a sent signal on the basis of both a received signal point composed
of a combination of received values in a diffused state of a sub-carrier within
a range, in which one modulation symbol is diffused, and a reference signal point
composed of the value which can be taken by the combination of the received values
in the diffused state. As a result, it is possible to prevent the influence of an
inter-code interference thereby to improve the receiving characteristics.
