Notes/Equations
- This model is used to simulate uplink DPDCH.
This model performs the same as the Agilent signal generator instrument ESG-D Option 100. - 2560 tokens are output each firing. DPDCH can be channelized on the I branch or the Q branch. The complex output data sequence is the spread and scrambled chips where SpreadCode and ScrambleCode specify the spread and scramble codes. The output sequence is repeated on a frame-by-frame basis.
- This model supports five data patterns: random, PN9, PN15, fixed repeated 8-bits, and from a user-defined file.
If the data pattern is 8-bits repeating, the bits to be repeated is set by RepBitValue. For example, if RepBitValue is set as 0 x 7a, bit sequence 0, 1, 1, 1, 1, 0, 1, 0 will be output repeatedly.
If data is from a user file, the user file name is specified by UserFileName. The file can be edited with any text editor. Separators between bits can be a space, comma, or any other separator. If the bit sequence is shorter than the output length, data will be output repeatedly.
