Hi Ravil,
Thank you for your response, am trying to simulate Simplex coding derived from Hadmard matrix, by implementing the code in the transmission using Mach-Zender, user defined pulse generator and NRZ signal, in addition to the CW laser source. Several steps I need to ask about, for example, in the coding part, how to implement (let us say) 3 bits code length,what is the rule of the leading zeros and trailing zeros?how to fill up the fiber length with the sequence based on the round trip time?And then what tools offered by the software to extract the signal after transmission? The urgent case for me now is the transmission and the coding part if you have an idea or toturials related. ( It seems I have many long questions ^_^) Thank you again
