Dear —all

How can to set Pseudo random bit generator ?what is the effect of generate random number ,number of leading zero,number of trailing zero , and random seed number ?

best regards…..

Hi Albaity,

As you probably know, each random number represents a bit of information. PRBG generates number of functions from ensemble which defined by number of elements “n” in this ensemble.

A seed number is a random variable which can be inserted in this ensemle.

Trailing and leading “0”s are defined numbers at the and the beginning of this ensemle (respectively). In my opinion, such pre-defined structure can be used for error correction or balancing “1”s and “0”s.

Will let you know if I get more information about it during my work.

thanks MR.Ravil

but HOW WORK optimization in optisystem to PRBG? when i changes randum seed index , bit error rate changes why?

best regards

Changing the random seed index will change the random sequence to a different random sequence. It is possible for the different sequence to perform better in some cases, this is why we recommend to simulate longer bit sequences, which should increase the accuracy of your simulation.
