Troubleshooting a Data Scrambler Block in Simulink for Wimax Systems

[tapan.aviator]

hi , i am designing a data scrambler block in simulink. it is for wimax system so i have designed one using delay units, XOR gates.i used the specification specified for the initial condition of delay elements and feedback connection according to wimax forum specifications, but i am not able to generate randomized output.im not sure if somethings wrong with the sample time or data type and that is why it is not generating proper random output. i have attached simulink model below. thank you very much.

There could be a few things wrong with your Simulink model. First, it is possible that your sample time is too slow, meaning that the data scrambler is not scrambling your data quickly enough or that the feedback loop is not being updated at the correct rate. Additionally, you may have the incorrect data type specified for your XOR gates and/or delay elements. Finally, you may need to adjust the initial conditions of your delay elements to get the desired random output. If none of these suggestions solve your issue, then it is possible that you have an issue with your design and would benefit from consulting with an experienced engineer.
