Link margin

In a wireless communication system, the link margin (LKM) is a critical parameter that measures the reliability and robustness of the communication link. It is expressed in decibels (dB) and represents the difference between the minimum expected power received at the receiver's end and the receiver's sensitivity. The receiver's sensitivity is the minimum received power level at which the receiver can correctly decode the signal and function properly.
