Information signal distribution apparatus for CDMA system

摘要

The apparatus includes a first data path which transmits user traffic data. At least a distribution unit is orthogonally provided on the first data path for distributing the traffic data by using an orthogonal code. A second data path is provided for bypassing the first data path. A control unit controls the data transmission path by selecting the length of an orthogonal code and a chip rate from the first and second data path in response on a digital bit rate. The control unit selects the first data path for the distribution of the traffic data using the orthogonal distribution unit if the product of the digital bit rate and the length of the code equals the chip rate otherwise the second transmission path is selected. A long-PN code generation unit distributes an output from the distribution unit using a long PN code with a fixed code offset, when the first data path is selected. When the second data path is selected the traffic data are distributed directly using a long PN code with different code offsets.
