Abstract

The present invention discloses a channel frequency spreading device for a CDMA system, including: an orthogonal sequence generating module, configured to generate orthogonal sequence sets; a storage module, connected to the orthogonal sequence generating module, and configured to store the orthogonal sequence sets; a control module, connected to the storage module, and configured to read available orthogonal sequences in the orthogonal sequence sets when receiving a user request control signal; and a channel machine, connected to the control module, and configured to receive user request data, and perform frequency spreading on the user request data according to the available orthogonal sequences and then output. The channel frequency spreading device for a CDMA system can improve the number of the sequences allocated by the cell, and solve the problem that the excessive users cannot communicate normally.
