| Popis: | Novel method of radio relay link bandwidth capacity improvement based on spatial signal processing by the wave front of the electromagnetic wave are presented. Test results of a variant of one-hop simplex radio relay link lab prototype with spatial signal processing both in the transmitting and receiving sites are shown. This prototype provides simultaneous parallel wireless transmission of two DVB-C radio signals with 64-QAM modulations at bit rates of 41.25 Mbps over 8 MHz bandwidth with the same carrier frequency of 10.56 GHz and with the same electromagnetic waves polarization at distance of 8 meters. This prototype can be used for research the possibility of radio frequency resource reuse and bandwidth capability improvement for radio relay links by applying spatial signal processing techniques. |
