**3.1.1.1 System parameters**

The link-level block diagram of the sliding correlation channel sounder for Single Input Single Output (SISO) channel is shown in Fig. 3. In the semi-sequential MIMO channel sounder (or SIMO channel sounder); there should be two parallel receivers.

Here we only focus on the indoor wireless MIMO channel for WLAN like devices. The measurement system supports 20/40MHz bandwidth by suitable RFIC [16][17]. The system parameters of baseband are listed in Table 1.
