Precondition and initiation

The Air Time Slot Resources (ATSR) must be conﬁgured for diversity.

The diversity initiates when the ATSR is taken into trafﬁc.

Figure 136 Diversity

One way to improve your performance on received signal is by using

diversity. This can be achieved by using two reception channels that are

independently inﬂuenced by fading. Both of the two insignals from the

antennas are combined in the receiver. The receiver uses the weaker

signal together with the stronger signal, with a factor proportional to

SNR (Signal to Noise Ratio) on each antenna.
