Performance Analysis and Optimization of HF Communication Over Bangladesh

Solar activity has a significant impact on the ionosphere, which can lead to adverse effects on the performance of high-frequency (HF) communication systems. Solar discharges cause expanded ionization, resulting in signal propagation that can cause disturbances. During a solar maximum, the ionosphere experiences even more dramatic changes due to the increased solar emissions, such as coronal mass discharges and solar flares. The ionosphere is ionized by solar radiation from the Sun, producing free electrons and ions, which can be measured through Total Electron Content (TEC) observations. TEC observations have become an essential tool for understanding the ionosphere’s structure and variations. The relationship between solar activity and the ionosphere is complex and dynamic, requiring ongoing research and monitoring to improve our understanding and predict potential impacts on high-frequency communication systems. By understanding the effects of solar activity on the ionosphere, we can better mitigate the risks to these systems and ensure their continued operation. This investigation led us to a better analysis of HF communication from the perspective of Bangladesh. Maximum usable frequency (MUF) is taken into the consideration for improving the performance of HF propagation. So that four different locations were used to take data that represents all the major parts of the country. In this context, TEC observations play a critical role in helping us to comprehend the ionosphere’s behavior and the effects of solar activity on it over Bangladesh.
