In this example, the SNR is greater than the receiver sensitivity, indicating that the system is feasible.
Any introductory tutorial will immediately introduce the decibel (dB) as the lingua franca of link analysis. Decibels are used because signal power can span many orders of magnitude; adding and subtracting logarithms is far easier than multiplying and dividing large numbers. The fundamental link budget equation is: Tutorial on Basic Link Budget Analysis.pdf
The represents the actual power radiated into the air. It is the sum of the transmitter power and the antenna gain, minus any losses from cables or connectors on the transmit side. In this example, the SNR is greater than
Let's consider a simple example of a satellite communication link: In this example
