Link budget calculator system for satellite communication

Link analysis basically relates transmitted power and received power and shows in detail how the difference between these two is accounted for. To this end the fundamental elements of the communications satellite Radio Frequency (RF) or free space link are employed. Basic transmission parameters, such as antenna gain, beam width, free-space path loss, and the basic link power equation are exploited. The concept of system noise and how it is quantified on the RF link is then developed, and parameters such as noise power, noise temperature, noise figure, and figure of merit are defined. The carrier-to-noise ratio and related parameters used to define communications link design and performance are developed based on the basic link and system noise parameters. Hence, a new system named as Link Budget Calculator is successfully designed to formulate the mathematical of link budget. The system analyzesand calculates basic formulas which are related to link budget by using the MATLAB software.
