dynamic sensitivity tetra

Hello!

Could anybody explain what is "Receiver Static Sensitivity" and "Receiver Dynamic Sensitivity".
It often appears in TETRA equipment specs.

Could anybody give also any reference to read?

Thanks in advance.

Receiver Static Sensitivity is the sensitivity without multipath (fading and reflections), and Dynimic Sensitivity is the RX sensitivity using a multipath environment (when the mobile is moving).

In other words,
feed the signal with cable, which makes free from other stray signals, Now reduce the power level of desired signal until satisfactory performance of the system. This sensitivity is static.
In the actual scenario when you do the same test is called Dynamic. here the Chanel effects are realized with the help of filters.
