7.1 Introduction
Whereas traditional simulation of non-CDMA or non-OFDMA systems is carried out in SEAMCAT by taki...
6.5.3 Some of the channels are blocked and some are available
This is a typical example. In such a scenario, the detection threshold is taken to a value of -80...
6.5.2 All the channels are blocked
In such a scenario, the detection threshold is taken to a lower value compared to the sRSS and no...
6.5.1 All the channels are available
In such a scenario, the detection threshold is taken to a value of 0 dB (Figure 160) much high...
