Fiber optics technology has been advancing rapidly for several decades, supporting the increasingly information-driven society and economy. It offers the means for global broadband communications based on single mode fibers (SMFs) which have almost reached its capacity limit. Hence research is presently directed towards transmission schemes that can exploit the spatial dimension. Development of few-mode fiber (FMF)-based optical transport systems is an attractive pathway to satisfy the high capacity demand. One promising solution would be to incorporate few mode fibers (FMFs) with mode division multiplexing (MDM) scheme that utilizes the orthogonal spatial modes of a FMF. The objective of this project is to analyze the performance of upcoming 5G waveforms using mode division multiplexed transmission over few mode fibers and thereby enable ultrahigh optical backhaul / front haul transport for next generation wireless systems.
The objective for this current work is to first identify a suitable 5G waveform among the multiple options proposed in the literature. To start with, the transmission and reception of the 4G Orthogonal Frequency Division Multiplexed (OFDM) waveform is analyzed, by simulation, over two modes LP01 and the LP11 of a Few Mode Fiber. It is shown that the signals in the individual modes can be successfully demodulated for a few tens of kilometers. In addition, the transmitter module for the generation of the 5G waveform (UFMC) using MATLAB has also been completed and the transmit signal compared with that of the OFDM signal.
