研究目的
Analyzing the Bit Error Rate (BER) performance of a system designed for high speed applications suitable for 5G communication, including the use of various optical filters to enhance system performance.
研究成果
The BER analysis and eye pattern prove that the performance of the system improves with the modified model while using various filters. The proposed system with pre-post amplifiers enhances the performance when different filters are used. The Bessel filter shows a better performance in comparison to the other filters being used, namely Trapezoidal, Gaussian, and Fabry Perot filter.
研究不足
The study focuses on simulation results, and real-world application may present additional challenges not accounted for in the simulation. The performance of the system is analyzed under ideal conditions without considering all possible atmospheric disturbances.
