Wireless channel qualities vary and degrade due to fading and interference. Cooperative communication has characteristics of spatial diversity and virtual antenna, and thus it can improve communication efficiency significantly. One of the essential design issues in cooperative communication is partner selection mechanism. In this paper, we propose a partner selection algorithm which utilizes two decision...
Increasing demand for high-speed and efficient multimedia transmission over wireless networks has driven tremendous research on enhancing the performance of multimedia communications over noisy channels. Multimedia applications increasingly require efficient transmission of still and moving images over wireless channels. In response to the rapidly increasing demand of the data-rate requirements, of...
In this paper, we propose a new multiple-input-multiple-output (MIMO) transceiver for transmitted-reference impulse-radio ultra-wideband (TR-IR-UWB) communications. The proposed scheme is capable of achieving full spatial and multi-path diversity orders while assuring a simple symbol-by-symbol decodability with analog autocorrelation receivers that do not require any kind of channel estimation. This...
