High Time Domain Resolution Indoor Channel Sounder for the 60 GHz Band

A very high time domain resolution channel sounder dedicated to the 60 GHz band indoor channel is presented. Based on Cox technique, it provides a 3 ns delay resolution. The value of the sliding factor k and the analysed impulse response length are electronically programmable, which allows a maximum Doppler analysis of more than 25 kHz. In all cases, the sampling frequency is minimised and direct PC hard disk storage is set up to perform very long acquisition sequences. Then, both long term and short term analysis of the impulse response are obtained. The first radio propagation measurement results are shown. Moreover, a BER measurement tool is under development. Simultaneous propagation and BER measurements will then be taken.
