Microwave Link

Pada system komunikasi menggunakan gelombang microwave ( link microwave ), adanya noise serta multipath fading dapat mengurangi dan menurunkan kinerja system komunikasi. Perambatan gelombang mikro dipengaruhi beberapa hal pada system penerimaan selain harus LOS ( Line Of Sight ) terdapat sinyal pantulan dari permukaan yang sangat menimbulkan interferensi ( sinyal multipath ). Dengan menggunakan teknik diversity maximal ratio combining pada system yang terkena noise dan fading digunakan melalui analisa BER ( Bit Error Rate ). Penggunaan simulasi penelitian  untuk mengetahui perbaikan system di penerima dengan membandingkan sebelum dan sesudah penggunaan teknik maximal ratio combining

The integralNHof neutral-hydrogen density along the line of sight is determined from the Kootwijk and Sydney surveys. The run ofNHwith galactic longitude agrees well with that of thermal continuous radiation and that of the optical surface brightness of the Milky Way.

AbstractThe interrelationship of half-widths and intensities for the red, green and yellow lines is considered. This is a direct relationship for the green and yellow line and an inverse one for the red line. The difference in the relationships of half-widths and intensities for different lines appears to be due to substantially dissimilar structuring and to a set of line-of-sight motions in ”hot“ and ”cold“ corona regions.When diagnosing the coronal plasma, one cannot neglect the filling factor - each line has such a factor of its own.
