Cooperative diversity has been shown to greatly improve performance of wireless networks.
The utilization of dynamic relays (cell users acting as relays) in cellular systems is of …

Relays in cellular systems are interference limited. The highest end-to-end sum rates are
achieved when the relays are jointly optimized with the transmit strategy. Unfortunately …

We propose a new compress-and-forward implementation for the relay channel based on
joint source-channel coding techniques. The relay performs scalar quantization of its …

In this paper, we analyze the impact of relays on the uplink performance of frequency-
division multiple-access cellular networks. We focus our analysis on decode-and-forward …

Advanced technologies in radio mobile systems have steadily increased the peak data rate
over years. However, the peak data rate can only be obtained in the most favorable …

In this paper we investigate the combination of rate and power allocation techniques in an
orthogonal cooperative scheme using infra-structured (fixed) relays, under the incremental …

本論文針對合作式通訊在低通道訊雜比的應用環境下提出一個新的中繼端傳輸方案.
中繼端利用純量量化器處理源自來源端的接收信號, 再利用分散式訊源編碼的同位子法以及多 …

It has been shown that cooperative work of base stations (BSs) is effective for the disaster
recovery, namely, even if BSs in some cells are destroyed and user terminals (UTs) should …

Global mobile data traffic has more than doubled in the past four years, and will only
increase throughout the upcoming years. Modern cellular systems are striving to enable …

For future wireless communication networks one of the major concerns for service providers
is to provide seamless connectivity to the end-users with quality of service (QoS) as high as …
