| Abstract(in English) | Maximal ratio combining digital beamformer has been studied to attain open-loop and automatic self-beam steering to both desired and multipath signals at the same time and dibersity combining of them, allowed by spatial digital signal processing. This paper describes the performace of this beamformer under the multipath signal arrivals with various path delay by means of numerical simulation. The results show the features of multidirectional beam steering when the path delay of the multipath signal is small and gain suppression to the multipath signal when its path delay is more than about one symbol. Moreover, improvement of the suppression by employing a low-sidelobe amplitude distribution is discussed as a method to reduce the inter-symbol interferece without null beamforming. |
