Title:
RADIO TRANSMITTING APPARATUS AND MULTICARRIER SIGNAL GENERATING METHOD
Document Type and Number:
WIPO Patent Application WO/2007/074777
Kind Code:
A1
Abstract:
A base station allowing mobile stations to efficiently remove interference
signals. In this base station (100), an encoding part (101) performs an error
correction encoding of transport data to generate a bit sequence comprising
systematic bits and parity bits; a repetition part (102) repeats, as a repetition
subject, only the parity bits out of the plurality of bits included in the bit sequence,
which is generated by the encoding part (101), so as to perform a rate matching;
a modulating part (103) modulates, after the repetition, the bit sequence to
generate symbols; an S/P part (104) parallel converts the symbols serially inputted
from the modulating part (103) and then outputs them to an IFFT part (105); and
the IFFT part (105) performs an IFFT processing of the symbols inputted from the
S/P part (104) and then maps them onto subcarriers in accordance with a predetermined
mapping pattern, thereby generating OFDM symbols.
