Performance Evaluation of GFDM in Underwater Wireless Optical Communication

Abstract

Underwater wireless optical communication (UWOC) was offered as a viable option for underwater communications that are suitable for high capacity and data transmission. This work includes the proposed, generalized frequency division multiplexing (GFDM) is considered in MIMO systems which provides the opportunity to fulfill the 5G technology. The Implementation of forward error correcting algorithm for channel encoding and decoding is to increase system performance. The FEC block code mechanism covered in this research is BCH. For successful channel estimation performances at the receiver side, we use symbol-by-symbol processing and MMSE decision feedback equalizers. The Monte Carlo (MC) applied to simulate and receive the impulse response of channel while accounting for scattering and absorption results. The investigation on different circumstances and performed through analysis of the UWOC channel for both diffusive and collimated links. The Monte Carlo simulation has been implemented to simulate the performance of BER, which accurately accounts for all channel impairments. The numerical results show that while performing symbol-by-symbol detection (SSD) significantly reduces ISI declines, spatial variety significantly reduces fading impairments.
