	1	A Survey of Downlink Non-Orthogonal Multiple Access for 5G Wireless Communication Networks显示文摘Non-orthogonal multiple access(NOMA) has been recognized as a promising multiple access technique for the next generation cellular communication networks. In this paper, we first discuss a simple NOMA model with two users served by a single-carrier simultaneously to illustrate its basic principles. Then, a more general model with multicarrier serving an arbitrary number of users on each subcarrier is also discussed. An overview of existing works on performance analysis, resource allocation, and multiple-in-put multiple-output NOMA are summarized and discussed. Furthermore, we discuss the key features of NOMA and its potential research challenges.	WEI Zhiqiang YUAN Jinhong Derrick Wing Kwan Ng Maged Elkashlan DING Zhiguo	2016	ZTE Communications2016，14，4：	8
	2	An Introduction to Transmit Antenna Selection in MIMO Wiretap Channels显示文摘This paper is a survey of transmit antenna selection-a low-complexity, energy-efficient method for improving physical layer security in multiple-input multiple-output wiretap channels. With this method, a single antenna out of multiple antennas is selected at the transmitter. We review a general analytical framework for analyzing exact and asymptotic secrecy of transmit antenna selection with receive maximal ratio combining, selection combining, or generalized selection combining. The analytical results prove that secrecy is significantly improved when the number of transmit antennas increases.
