4x4mimo
A 2x2 multiple-input multiple-output (MIMO) architecture
using dual-polarized antennas (DPAs) is considered
with orthogonal frequency division multiplexing (OFDM). The
performance of DPAs is evaluated for adaptive polarization
(AP) transmission techniques in time-varying multipath channels
impaired by polarization mode dispersion (PMD) and
polarization-dependent loss (PDL). AP transmission techniques
considered include power gain maximization, polarization dispersion
minimization for interference avoidance, polarization
multiplexing with waterfilling, and a suboptimal multiplexing
strategy that enables direct recovery of the polarization multiplexed
streams, thereby simplifying the design of the receiver.
Measured time-varying dual-polarized channel realizations from
mobile-to-mobile experiments are used to estimate the capacity,
diversity, and interference avoidance performance of the adaptive
approaches.

模拟段式管理内存分配与回收
把程序按内容或过程（函数）关系分成段，每段有自己的名字。一个用户作业或进程所包含的段对应于一个二维线形虚拟空间，也就是一个二维虚拟存储器。段式管理程序以段为单位分配内存，然后通过地址映射机构把段式虚拟地址转换成实际的内存物理地址。(The program is seperated to sections by content or progress(function),every section has its name.)
