Filter-and-forward distributed beamforming for relay networks in frequency selective fading channels
14 years 2 months ago
A half-duplex distributed beamforming technique for relay networks with frequency selective fading channels is developed. The network relays use the ï¬lter-and-forward (FF) strat...
