PuTTY是一个Telnet、SSH、rlogin、纯TCP以及串行接口连接软件。较早的版本仅支持Windows平台，在最近的版本中开始支持各类Unix平台，并打算移植至Mac OS X上。除了官方版本外，有许多第三方的团体或个人将PuTTY移植到其他平台上，像是以Symbian为基础的移动电话。PuTTY为一开放源代码软件，主要由Simon Tatham维护，使用MIT licence授权。随着Linux在服务器端应用的普及，Linux系统管理越来越依赖于远程。在各种远程登录工具中，Putty是出色的工具之一。Putty是一个免费的、Windows x86平台下的Telnet、SSH和rlogin客户端，但是功能丝毫不逊色于商业的Telnet类工具。目前最新的版本为 0.68 latest release(PuTTY is a Telnet, SSH, rlogin, pure TCP, and serial interface connection software. The earlier version supported only the Windows platform, and in recent versions began to support various Unix platforms and was intended to be ported to Mac OS X. In addition to the official version, there are many third party groups or individuals that migrate PuTTY to other platforms, such as Symbian based mobile phones. PuTTY is an open source software that is maintained primarily by Simon Tatham and licensed using the MIT licence. With the popularity of Linux applications on the server side, Linux system management is becoming more and more dependent on remote. Putty is an excellent tool for various remote login tools. Putty is a free, Telnet, SSH, Telnet, and rlogin client on the Windows X86 platform, but it is no less functional than the business class tools. The latest version is 0.68 latest release)

基于esprit算法的宽带信号（线性调频信号）doa估计(DOA estimation based on esprit)

为了提高MIMO-OFDM系统的数据传输率和频谱利用率,提出一种新的自适应算法。该算法在保证信道质量所需误码率和总发射功率的前提下,按照各个子载波衰落程度动态地分配比特和功率,使系统的总数据传输速率最大。理论分析得出,该算法降低了系统运算复杂度,能很大地改善系统的整体性能。(In order to improve data transmission rates and spectrum efficiency of MIMO-OFDM systems,this paper proposes a new adaptive algorithm. While the channel transmission quality to meet the requirements of a certain target BER(bit error rate) and total emissive power,according to each sub-carrier decline degree to adjust each sub-carrier modulation method freely,try to minimize the total data rate of system. Theory analysis shows the algorithm can reduce system complexity and improve overall performance of the ...)
