Option 200 Calculating Downlink Scramble Codes
Calculating Downlink Scramble Codes
The Option 200 signal generator implements scrambling codes for downlink OCNS and
DPCH channels in compliance with the 3G TS 25.101 V3.3 specification. This is done
through the use of the Scrambling Code (primary scramble code) field, located in the BS
setup menu, and the SecScr Code OS (secondary scramble code offset) fields located in the
OCNS and DPCH Physical Channel Setup menus. These fields are linked so that an entry
to any field affects the actual scramble code. To better understand the relationship, refer to
the following formula:
The primary and secondary sets are determined by the SecScr Code OS field values. If the
SecScr Code OS field value is zero, then the scramble code is in the primary set. Any
non-zero entry enables the secondary set. The SecScr Code OS field value has a range of
0 through 15.
A primary scramble code is the product of the Scrambling Code field value and 16.
Therefore, the primary scramble code set contains all the multiples of 16, from 0 through
8176.
A secondary scramble code is the sum of the non-zero SecScr Code OS field value and the
primary scramble code. The secondary scramble code set uses the numbers in between the
multiples of 16.
Thus, all numbers from 0 through 8191 are available for scramble codes.
Refer to the following for examples of scramble codes generated with the primary and
secondary sets:
Where n = scramble code Range: 0 to 8191
i = Scrambling Code field input Range 0 to 511
k = SecScr Code OS field input Range: 0 to 15
Where n = scramble code
i = Scrambling Code field input
k = SecScr Code OS field input
A: Primary set B: Secondary set
i = 6 i = 8
k = 0 k = 7
n = 96 n = 135
n 16 i×()k+=
n 16 i×()k+=
