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.
L'invention porte sur un randomiseur (101) qui rend identique le nombre de 1 et le nombre de 0 des donn~es. Un codeur (102) effectue le codage des donn~es en respectant une ~galit~ entre les 1 et les 0. Un ~taleur ~ modulation HS-DSCH (103) effectue une modulation modulo-n des donn~es cod~es et effectue ensuite un ~talement des donn~es au moyen d'un code d'~talement.- D'autre part, un signal commun connu est soumis ~ la modulation modulo-n dans un ~taleur ~ modulation CPICH (104) et ~ ~talement au moyen d'un code d'~talement. Le signal commun connu soumis ~ l'~talement dans l'~taleur ~ modulation CPICH (104) est multiplex~ avec les donn~es qui ont ~t~ soumises ~ ~talement dans l'~taleur ~ modulation HS-DSCH (103) par un multiplexeur (105). Le signal d'~mission multiplex~ est ~mis depuis un ~metteur radio (106). Il est donc possible, avec un circuit de configuration simple, d'obtenir avec pr~cision un point de r~f~rence du plan I-Q.
