This algorithm utilizes the common nullspace of a set of fourth-order cumulant matrices to identify an unknown MIMO channel impulse response up to a constant monomial matrix. 该算法利用一组四阶累积量矩阵的零空间把一个未知MIMO信道的冲激响应辨识成一个常的单项矩阵。
On the basis of studying the monomial matrix it is extended the result of the finite field GF ( 2~ m) to the most general finite field GF ( p~ m), where p is any prime number. 对单式阵群作一个较详细的研究,并将GF(2m)上线性码的自同构群的一些结论推广到最一般的有限域GF(pm)上去,这里的p是任意的素数。
Besides, we also discuss characteristics of monomial matrix for proof main result of this paper. 此外,为了证明本文的主要结果,我们又讨论了单项矩阵的特性。
Based on the special matrix operations including Kronecker product, Hadamard product and vectorization, the integration of monomial integrand on simplex domain is expressed in matrix form and a recursive formula for the simplex integration is presented. 基于Kronecker积、Hadamard积和拉直等矩阵特殊运算,将单项式函数在单纯形上的积分表示为矩阵形式,提出了单纯形积分的递推公式。
