不同于传统秘钥加密技术,无线物理层安全理论技术是根据主窃信道传输速率的差值等特征信息来从信息论的角度降低窃听者获取的有用信息量。 在理想的窃听信道模型中,只要保密容量(主窃听信道容量差)大于0,系统就可以达到保密通信。%在引入信号衰落之后,保密通信只以一定的概率实现。 本文通过建立中断概率模型来对通信系统的保密性进行仿真。 本文主要研究性能中的保密速率和主窃信道信噪比这两个指标。在系统所需保密速率是定值的条件下,主窃信道信噪比之差越低,通信的保密性越好。通过采用MIMO技术中的波速成形技术,合法信道中的信道容量可以被大幅度提高,进而大幅度降低中断概率。环形干扰技术不仅可以降低窃听信道信噪比,而且对主信道的传输速率不会产生负面影响。经过使用Alamouti编码技术,可以很好的解决由于天线数量增多而导致译码复杂度增加的问题。

Employing multiple transmit and receive antennas, namely using multi-input multi-output (MIMO) systems, has proven to be a major breakthrough in providing reliable wireless communication links. Since their invention in the mid-1990s, transmit diversity, achieved through space-time coding, and spatial multiplexing schemes have been the focus of much research in the area of wireless communications.

In order to improve the spectral efficiency in wireless communications, multiple antennas are employed at both transmitter and receiver sides, where the resulting system is referred to as the multiple-input multiple-output (MIMO) system. In MIMO systems, it is usually requiredto detect signals jointly as multiple signals are transmitted through multiple signal paths between the transmitter and the receiver. This joint detection becomes the MIMO detection.

When we started thinking about writing the first edition of this book a few years ago, we had been working together for more than five years on the borderline between propagation and signal processing. Therefore, it is not surprising that this book deals with propagation models and design tools for MIMO wireless communications. Yet, this book should constitute more than a simple combination of these two domains. It hopefully conveys our integrated understanding of MIMO, which results from endless controversial discussions on various multi-antenna related issues, as well as various interactions with numerous colleagues. Obviously, this area of technology is so large that it is beyond our aim to cover all aspects in details. Rather, our goal is to provide researchers, R&D engineers and graduate students with a comprehensive coverage of radio propagation models and space–time signal processing techniques for multi-antenna, multi-user and multi-cell networks.

Due to the asymmetry between the amount of data traffic in the downlink and uplink direction of nowadays and future wireless networks, a proper design of the transceivers in the broadcast channel is inevitable in order to satisfy the users’ demands on data rate and transmission quality. This book deals with the optimi- zation-based joint design of the transmit and receive filters in a MIMO broadcast channel in which the user terminals may be equipped with several antenna ele- ments.
