PROJECT TITLE :

Symbol Error Rate Model for Communication Using Femtosecond Pulses for Space Applications

ABSTRACT:

In some emerging satellite applications, it is of paramount importance to accurately live the distance between satellites in formations. Vary measurement systems primarily based on femtosecond lasers have been steered as very precise solutions that would be incorporated into satellites. It would be fortuitous to take advantage of the same laser link for both the gap measurement and communication, so achieving two functions with significantly reduced payload weight and size compared with that might be achieved if the two tasks were performed separately. In this letter, we have a tendency to propose to modulate the ranging femtosecond pulses to hold communication info. The proposed modulation is in the frequency domain, cashing in on the wideband property of femtosecond pulses. The method hinges on the special characteristics of the femtosecond pulse, that encompasses a terribly broad frequency spectrum alongside its ultrashort time duration. We have a tendency to analyze the multiple-inverse-pulse-position modulation (MIPPM) methodology. The most plan of the MIPPM is that the ON–OFF modulation of every spectral part, whereas every modulated image includes all spectral parts and solely few spectral parts are within the OFF state at any given time. We analyzed the performance of the proposed system in terms of symbol error rate for a given set of parameters.
