“…Moreover, traditional nonlinear effect equalization method designed for optical OFDM can't be directly used in O-OFDM/OQAM. Several researches on decreasing the PAPR for O-OFDM/OQAM have been published [36,37]. However, there is few existing systematically discussion about nonlinear compensation methods based on receiver signal processing, and further research is quite necessary for future optical OFDM/OQAM development.…”

“…Because of that mitigation of CD is important in designing the high performance optical communication [13]. In the past, various CD mitigation have been proposed via signal processing and through programing [14]. There are several issues are encountered when mitigating the CD via programming and signal processing [15].…”

Chromatic Dispersion (CD) is the important effect that is considering for optical communication system design as it broadens the pulse during the propagation along channel resulting in pulse overlapping and ultimately bit errors raises. The increment in bit error, in result reduce the performance of optical system. Therefore, mitigation CD is necessary in order to improve the performance of optical communication system. There are several techniques of mitigating CD have been proposed and all based on coding based and this will create issues for the communication design engineer that every time the parameters need to be revised. In order to avoid this issue, the ease for the system design engineer has been created in designing the Graphical User Interface (GUI). In this work, GUI is designed and developed that will request the parameters need to be select for the optical system and it will describe the all process for mitigating it from the system. In the first, the communication system designer have to select the Transmission along with modulation and after that transmission at distance is asked in terms of km. The CD is mitigated uses least mean square technique and Fast Fourier Transform method. The further smoothing of signal is improved by Pulse shaping via using the raised cosine filter. In the end, the original signal and the compensated signal are defined. The BER is also calculated to show whether the reduction through DSP is performed. The GUI is developed in MATLAB and every button backhand the strong coding is used in C++ for developing the system. The designed and developed system offers the ease of use for the communication engineer, in which on one platform the user can observer well the optical system instead of programming.
