In recent years, 4G LTE networks have been deployed by some operators and some of them also sell Femto Cell service in the market. As a kind of Heterogeneous network in cellular communication, lots of work have been published in last few years. However, considered in next generation cellular communication system, some challenging features have been planned like: A super-efficient and fast mobile network...
In this paper, we investigate the theoretical per-node transmission limit of hybrid wireless networks over fast fading channels. We first formulate a hybrid wireless network model, in which a wired network of base stations is deployed to support long-range communications between wireless nodes. Two types of transmission mode in hybrid wireless network, the so called intra-cell transmission mode and...
In this paper, experiments on through-wall human being detection using ultra-wideband (UWB) radar PulsOn 220 in monostatic mode are carried out. For periodic respiratory motion of human target, the detection techniques employed are normalized difference square matrix method, and reference moving average method with Discrete Fourier Transform (DFT). The experimental results for human target detection...
Considering the potential interference of ultra-wide hand (UWB) system to OFDM based narrowband wireless communication system, such as IEEF. 802.1 In system, this paper investigates the optimal power allocation scheme for Impulse Radio UWB (1R-IIWB) user in order to maximize the total transmission rate of UWB with the constraints that its interference to IEEE 802.11n user is below a certain threshold...
In this paper, we investigate the capacity of wireless hybrid networks, in which a wired network of base stations is used to support long-range communications between wireless nodes. We introduce the multiple access technique by allowing more than one source node to transmit simultaneously and utilizing successive interference cancellation to decode information at the destination node. Our results...
