<strong>system</strong> used by KTH is self-made based <strong>on</strong> commercial laboratory equipment. All measurements <strong>system</strong>s<br />
are described in more detail below. For further informati<strong>on</strong> the reader is advised to c<strong>on</strong>sult the web pages<br />
under the <strong>link</strong>s given in Table 5.1.<br />
5.1.2.1 PropSound <strong>channel</strong> sounder<br />
Figure 5.1 presents a schematic diagram of PropSound <strong>channel</strong> sounder. The sounder <strong>system</strong> c<strong>on</strong>sists of<br />
separate transmitter <strong>and</strong> receiver parts, which both are c<strong>on</strong>trolled through a pers<strong>on</strong>al computer. Both TX<br />
<strong>and</strong> RX are able to c<strong>on</strong>trol RF switches, which are synchr<strong>on</strong>ized in order to make time-multiplexed<br />
MIMO measurements.<br />

NOK <strong>and</strong> EBIT both have a PropSound <strong>channel</strong> sounder. However, the <strong>system</strong>s have somewhat different<br />
characteristics. The key features of the EBIT PropSound <strong>channel</strong> sounder are listed in Table 5.2, while the<br />
NOK PropSound features are listed in Table 5.3.<br />
