**3.1.3 GUI**

To provide a user friendly human interface, we design a MATLAB based GUI. The real time data stream is accessible from the specific application software through a function call of the COM-Server from IAF. The software can provide several channel information from the original measured data. These channel information include channel impulse response, channel transfer function, delay power profile, scattering function and Doppler power spectrum. Fig. 7 is an indoor channel test result for example.
