With the increasing number of wireless communication devices, there may be a shortage of
non-licensed spectrum, and at the same time, licensed spectrum may be underutilized by …

In this paper, we present a novel signal to noise ratio (SNR) estimation technique using
Constant Amplitude Zero Autocorrelation (CAZAC) time synchronization preamble in …

Cooperative communications aim to gain spatial diversity from stations cooperating during
data transmission without requiring multiple transceiver antennas on the same station …

研究表明, 协作中继选择能提高无线中继网络的鲁棒性和能效. 文中研究一个多接入中继信道,
包含2 个信源, N 个中继和1 个信宿. 中继节点为半双工, 对两个信源的信号采用非再生的网络 …

Power line communication (PLC), a technology that uses the existing infrastructure for
electric power for the provision of data, is fast becoming the choice for smart grid system. As …

In a wireless network with multiple amplify-and-forward (AF) nodes, the many-to-many
cooperative communication is achieved through the novel concept of space-time network …

This article proposes and analyzes a distributed probabilistic selection protocol in which
several nodes perform a random access competition on a shared slotted channel. Nodes …

Cooperative communication is considered one of efficient techniques to overcome fading in
wireless networks since it can achieve spatial diversity. Employing all the relays in the …

We evaluate by real-world measurements two cooperative relaying protocols for industrial
sensor networks: the first one employs a periodic relay selection scheme, where relays are …

This paper reports on an experimental study about some benefits of cooperative relays in
mobile wireless communications. A basic technique for cooperative relaying is implemented …
