空时编码之多输入多输出
应用背景
当天线的数目一定时,空时格码(STTC)的译码复杂度与天线的个数和数据速率成指数增长。为了解决译码复杂度的问题,Cadence公司的Alamouti首先提出了一种使用两个发送天线的传输方法,采用两个发送天线和一个接收天线,这种算法的性能与采用最大比合并算法(一个发送天线,两个接收天线)的性能是相同的。具体算法介绍如下。
关键技术
(1)空时网格码(STTC):空时网格码最早是由V.Tarokh等人提出的,该空时编码系统中,在接收端解码采用维特比译码算法。空时网格码设计的码子在不损失带宽效率

ChebyshevExpansion
给定一个普通多项式p(x),用列向量表示,阶次从高到低排列,此函数返回p(x)的切比雪夫多项式展开的系数,返回的的结果也是一个列向量,同样按切比雪夫多项式的阶次从高到低排列
另外该函数用cos(x)项傅里叶级数展开一个多项式(
ChebyshevExpansion.m by David Terr, Raytheon, 5-26-04
Given a polynomial f(x) of degree n expressed as a row vector of coefficients of x^k with
highest power on the left, expand f(x) as a sum of scalar multiples of
Chebyshev polynomials, i.e. return the column vector of coefficients a_k with k
running from n to 0 from top to bottom such that f(x) = sum_{k=0}^n{a_k P_k(x)}.)
