—An amplify-and-forward (AF) wireless relay network consisting of a one-source-one-destination node pair and cooperative multiple N relay nodes is proposed in three adverse wireless communication environments, i.e., jamming, node geometry, and channel uncertainty. Based on the minimum mean square error (MMSE) criterion, the optimal amplifying relay matrix(More)
This paper presents an optimal solution for amplify-and-forward (AF) single-input multiple-output (SIMO) and multiple-input single-output (MISO) wireless distributed relay networks. The optimal solutions are determined based on minimum mean square error (MMSE) criterion for optimum nondiagonal and diagonal relay amplifying matrices under the transmit power(More)
As technology progresses, people expect the light to be able to paint images that are as close as they can be to the real world. People also have the desire to recreate what already exists in reality as a three-dimensional object. This study is focused on research on media art using volumetric display techniques and an artwork using the principle which is(More)
The development of digital media has ended the conceptual and technical division between the gaming industry and the performing arts. Digital games based on computers provide the experience of enhanced immersion in the game as one enters a virtual environment and leads the story by selecting and manipulating independently. In the case of media performance(More)
