Leaky coaxial (LCX) cable can be used as antenna for wireless communication system and wireless power transfer which can be widely applied for many application scenarios including wireless service for IoT, automated factory using a large number of wireless devices. We have designed that one LCX cable can be used as two antennas which can releases the space requirement of MIMO deployment for wireless application. In this paper, we will further evaluate the 4-by-4 LCX-MIMO channel using one composite cable with two LCX cables. In addition, we also propose a low-complexity power allocation method for the LCX-MIMO system with the user's positional information (PI). The results show that the capacity is promising when the spacing between LCX cables is small as to 2cm. In addition, our proposed low-complexity power allocation has better capacity than that of using equal power allocation when SNR value is over the low range.

Success prioritized distributed coordination function 査読

IEICE COMMUNICATIONS EXPRESS 5 ( 9 ) 303 - 308 2016年

In this letter, we present a random access protocol with success priority, success prioritized distributed coordination function (SP-DCF), based on IEEE 802.11 DCF. Success stations (STAs) are prioritized contentionlessly to transmit the next data frame in the transmit queue in a random manner. We develop a performance analysis model of SP- DCF which enables us to estimate a variety of performance indexes such as the throughput or the frame discard rate (FDR) in a high accuracy for saturated wireless networks. The numerical analysis and simulation results show that the proposed SP-DCF achieves higher throughput and lower FDR as compared with the conventional DCF especially for heavily-congested wireless networks.

Physical layer network coding using THP for Bi-directional MIMO relay systems

Lengchi Cao, Satoshi Denno

2015 IEEE Wireless Communications and Networking Conference, WCNC 2015 1482 - 1487 2015年6月

記述言語：英語掲載種別：研究論文（国際会議プロシーディングス）出版者・発行元：Institute of Electrical and Electronics Engineers Inc.

Bi-directional relaying has been demonstrated to raise transmission throughput intensively as large as twice in throughput by applying physical layer network coding (PNC) when a pair of terminals exchange information via relay. With the aim to enhance the performance of relay system based on decode-and-amplify (DF) strategy, we propose a PNC scheme using Tomlinson-Harashima precoding (THP). Assuming the same broadcast scheme, our proposed scheme shows better performance than conventional linear precoding scheme. To reduce the transmission power without increasing bit error rate (BER), we further introduce a power controlling (PC) structure. It is proved that the transmission power and BER can both be reduced with the power controlling method.

In this paper, we propose a distributed coordination function with successful transmission priority (DCF-STP) based on IEEE 802.11 DCF. DCF-STP will enhance the throughput and reduce the frame discard rate (FDR) in wireless networks because the wireless station (WS) just after the successful transmission has an opportunity to transmit the next frame without contention. We also develop a performance analytical model which enables to estimate the throughput, FDR, and the average number of frame retransmissions with high accuracy for saturated wireless networks. The simulation results show the validity of the developed performance analytical model of DCF-STP and the characteristics in the coexistence of the conventional DCF and the proposed DCF-STP.
