C++模板

这一周是属于拓展性的一周，因为这一周发现了C++的另一个强大之处，就是它的容器和模板。

这一周的学习过程大概是这样的，自从发现了模板的作用之后，就打算写一个矩阵的模板类。从网上下了一个有问题的程序代码，然后就是边看书边写，刚开始有点自己想当然的写，然后调试通不过，就翻书找，查找问题所在。三四天的连续奋战，终于搞定了模板类的编写，同时用到了valarray 和 complex标准库中的模板。以这些为基础，再加上上周写的alamouti程序代码，很快就完成了combating synch errors in co-relays论文中的算法程序。

5月已经来了，这个月重点托业，同时看论文，看C++方面的书，用C++写仿真程序。
几件要做的事：
1 修改论文，选择杂志发表； 2 参加研三答辩，注意学习。有机会去听下重邮那位师兄的答辩；3 多看书，少上网。

今天生日

今天生日，平平常常的过吧。挺佩服同学说的一个人，为了512他生日那天过的有意义，在网上组织，生日那几天去北川支教。
上周所作的工作：
1 小论文内容、格式搞定，发给老板了。
2 托业做了两份听力练习，不是太理想，存在问题：很难长时间集中注意力，缺乏练习，缺乏意志！！！！
3 用C++完成alamouti经典论文的仿真（有兴趣要代码可以留邮箱，我可以发给他），一方面起到练手的作用，另一方面，其他程序都可以以此为原型，进行修改。不能太依赖matlab，师兄给的建议。在编程过程中遇到一些问题，都已解决，练习目的达到。

下周安排：
1 备考托业放在首位，必须坚持，下周搞定两篇听力练习。通过多种途径学英语
2 做combating synchronization errors in cooperative relays论文的仿真，指导本科毕业设计。
3 多数时间用来看书，主要针对LTE和C++。

五一忽略，时间不多了

关于头文件中为何要用static

static在头文件中使用的意义：

举个例子:

#ifndef __debug_h
#define __debug_h

#include
#include
#include
#include

static int __verbose = 0;
#define __have___verbose 1
static int __daemon = 0; /* is program daemon? */
#define __have___daemon 1
static int __debug = 0;
#define __have___debug 1

#ifdef __cplusplus
extern "C"{
#endif

static void _debug(const char* fmt, ...)
{
va_list arg;
char buf[8192];

va_start(arg,fmt);
vsnprintf(buf,8192,fmt,arg);
#ifdef DEBUG
if(__daemon){
syslog(LOG_DEBUG|LOG_USER,buf);
}else{
fputs(buf,stdout);
}
#endif
}

static void _verbose(const char* fmt,...)
{
va_list arg;
char buf[8192];

if(!__verbose)
return;
va_start(arg,fmt);
vsnprintf(buf,8192,fmt,arg);

if(__daemon){
syslog(LOG_DEBUG|LOG_USER,buf);
}else{
fputs(buf,stdout);
}
}

#ifdef __cplusplus
}
#endif

#endif

为何上面的都用static 来修饰呢？

如果没有static
当有两个文件a.c 和 b.c
如果a.c b.c都用到了debug.h
那么
debug.h + a.c ===> a.o
debug.h + b.c ===> b.o
gcc a.o b.o -o target
时，a.o和b.o中都同时有__debug,__daemon,__verbose,和_debug,_verbose
的定义，所以链接的时候就回出现multi-definition，为了避免这个
用static声明后，即使有同名的函数或变量出现，但由于static的局部性
不会影响到其他到模块，所以这就很好的避免了上面的multi definition的问题

假期归来，收心啦

陪女朋友一周，一个字：累；俩字：幸福。
荒废学业也已经一周了，转眼间4月已经快到头了，按照原来的计划，接下来有两项重要工作：修改论文和备考托业。

关于论文，数据一直有些牵强，按照自己的想法改了再试试。不想在这上面花费太多时间，毕竟它不能带来太大能力方面的提升。

至于托业，应该有足够的重视，毕竟六级分数已经定型了，再加上报名又花了那么多钱。想法是起早，从明天到5月31号，早上8点之前到实验室，人少，方便学英语。每天至少用3到4个小时学英语。同时应该注意联系口语！

至于LTE链路仿真，起初没有意识到任务的艰巨性，别人的硕士论文内容，自己却想顺便做做。现在应该调整思路，要系统学习LTE的知识，但应把研究和仿真重点放在和自己研究方向相关的部分上。

C已经好久没碰了，罪过罪过。这方面也应该转变下思路，一直以来，一直想自己编程序，是都能实现，但程序并不见得就好。接下来应该多看些别人的程序，不能做井底之蛙。

总之，目标很明确，一切为了把基础打扎实，提升能力，为找工作做准备。现在不是为我一个人而努力。

关于讨论会

今天下午讨论会，把我最近的工作以及论文的主要内容给大家讲了讲，加上提问问题总共一个半小时。

并没有完全把想将的讲清楚，但也正常，要能讲得很清楚就不正常了。这也是种能力呀，需要锻炼。这是第二次讲东西，去年上了一学期课对自己还是挺有帮助的。作讲座，指导思想很清楚，首要目的是让别人听懂。今天有些内容自己都感觉没讲清楚，不过最主要的内容还是讲清楚了的。

以后要珍惜这种机会，多多锻炼。

第六周——小论文

实验室网络不正常，再加上清明放假，上周感觉有点乱。

主要做的工作：
准备了一些小论文材料，翻译了一篇英文文章，打算以那篇论文为框架。写作能力叫一个差呀。

在这个过程中发现了论文中一个公式是错的，程序也是按照错的公式写的，所有程序又要重跑一遍。以后一定要注意，要么推导一下公式要么用某种途径验证公式的正确性。没想到IEEE上面的文章也会有错。

做讨论会需要的PPT，这个过程收获还是挺大的，有些东西自以为弄清楚了，但想怎样去给别人讲的时候发现还是没弄太明白，然后就想的多了，学的也就多了。

在看LTE的过程中意识到了空间分集和空间复用的区别，分集追求可靠性，复用追求高速，具体区别不多说了。

上行MIMO：LTE中提出两个终端天线配对形成多天线，然后按照类似于分层空时码的方式发送信号。这周把这块好好看看。

一篇3GPP上下的关于协作或者说中继的文章，研究一下。

周三下午演讲，周四去虎溪参加党组织生活，周五准备迎接老婆。
下了一个Turbo码的C++程序，写的不错，注释清晰，好好研究一下。看别人的程序太少了，多学学。
