A randomizing unit (101) makes the number of 1 and the number of 0 of the data 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.

Why it's free to use
- Filed February 17, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 17, 2023.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
