massive mimo Fundamentals, Opportunities and Challenges
应用背景Massive multiuser MIMO (MISO):
◮ M ≫ K ≫ 1 (think 100 × 10 or 500 × 50)
◮ coherent, but simple, processing
◮ Potential to dramatically improve rate & reliability
◮ Potential to drastically scale down TX power
◮ Not only theory, at least one known testbed (64× ∼10)
关键技术
Massive MIMO Operation
Not enough resources for pilots & CSI feedback, so operate in TDD.
◮ On the uplink,
◮ acquire CSI from uplink pilots and/or blindly from data
◮ detect symbols
◮ M ≫ K ⇒ linear processing (MRC, ZF, MMSE) nearly optimal
◮ On the downlink,
◮ use CSI obtained on the uplink
◮ make necessary adjustments based on reciprocity calibration
◮ apply multiuser MIMO precoding
◮ simple precoders desirable (and very good!): MRT, ZF, MMSE, ...
◮ MRC/MRT operation
◮ intracell interference will appear as

蒙特卡罗方法又称随机抽样技巧或统计试验方法。半个多世纪以来,由于科学技术的发展和电子计算机的发明 ,这种方法作为一种独立的方法被提出来,并首先在核武器的试验与研制中得到了应用。蒙特卡罗方法是一种计算方法,但与一般数值计算方法有很大区别。它是以概率统计理论为基础的一种方法。由于蒙特卡罗方法能够比较逼真地描述事物的特点及物理实验过程,解决一些数值方法难以解决的问题,因而该方法的应用领域日趋广泛。
-Monte Carlo method known as random or statistical skills test method. More than half a century, the development of science and technology and the invention of the electronic computer, this method as an independent method was raised and the first nuclear test and research has been applied. The Monte Carlo method is a calculated, but with the general numerical method a great difference. It was based on the theory of probability and statistics-based approach. As the Monte Carlo method can vividly describe things and the physical characteristics of the experimental process, numerical methods to solve some difficult problems, the result of the increasingly extensive application areas.

用C++动态TSP问题
应用背景一个旅行推销员是准备一个大的销售之旅。在他的家乡,提着手提箱,他将进行一次旅行,他的每一个目标城市被访问一次然后回家。鉴于城市之间的两两距离,在参观他们的最佳顺序是什么,从而减少整体的距离?为城市的1,……,N,推销员的故乡1,让a ; ;(dij)是城际间的距离矩阵。我们的目标是设计一个旅行的开始和结束在1,包括所有的其他城市是一次性的,并具有最低的总长度。图中显示了一个涉及五个城市的例子。 ;关键技术让我们马上进入DP。那么什么是适当的子问题求解TSP?在这种情况下,最明显的部分解决方案是一个旅游的初始部分。假设我们在市1的要求开始,参观了几个城市,现在在城市的什么信息是我们为了扩大这部分旅游需求?我们一定要知道,因为这将决定哪些城市未来最方便的访问。我们还需要知道所有访问的城市到目前为止,所以我们不要重复任何人。在这里,然后,是一个合适的子问题。
