Abstract :
Experimental results are presented for the multipath channel characterization of a 40 MHz wide RF channel in the 4 GHz band. The 40 MHz wide test signal is transmitted over a 52 km hop. The space diversity receiver combines the test signal using a continuous phase maximum power technique. Channel responses are measured on the main antenna, the diversity antenna, and the combined channel. The effects of bandwidth on in-band power-difference are also described.<>
