TRANSMISSION APPARATUS AND TRANSMISSION METHOD

WIPO Patent Application WO/2003/069868

A1

A randomizing unit (101) makes the number of 1 and the number of 0 of the data identical. A coding unit (102) performs coding of the data in which the number of 1 and the number of 0 have been made identical. An HS-DSCH modulation spread unit (103) performs multinary modulation of the coded data and then performs spread processing of the data by using a spread code. On the other hand, a common known signal is subjected to multinary modulation in a CPICH modulation spread unit (104) and the spread processing by using a spread code. The common known signal subjected to the spread processing in the CPICH modulation spread unit (104) is multiplexed with the data which has been subjected spread processing in the HS-DSCH modulation spread unit (103) by a multiplexing unit (105). The transmission signal multiplexed is transmitted from a radio transmission unit (106). Thus, with a simple circuit configuration, it is possible to accurately obtain a reference point of the I-Q plane.
