Offline system analysis of high frequency digital signal / Mohd Zaidi Che Mat
This project highlights the significant of the high frequency (HF) communication system in communication field. With a frequency spectrum between 3 to 30 Mhz an ionosphere often reflects the signal frequency very well during transmitting the signal. Hence, the HF communication can be done in long di...
