CVX无法直接表示 log2x ,可以使用log(x)/log(2)表示。 由于trace(X)中,X必须是二阶方阵,如果使用W(M,M,K)表示提升后的波束成形矩阵,可以创造一个长度为K的数组来装每个W(:,:,k)的迹 CVX可以对向量或矩阵进行整体操作。 尽量不要使用SDP模式,因为SDP模式会修改矩阵不等式的定义 CVX一般不允许出现...

where the\(\alpha(p_n)\)term grows very slowly compared to the\(\log_2\)term. Indeed, for\(p_n\leq 4096\), we have verified that\(\alpha(p_n)\)is usually 1 or 2, but occasionally 0 or 3. Similar results are obtained for\(0 < p < 1\)and\(p < 0\). ...
The DCP ruleset is a set of sufficient, but not necessary, conditions for convexity. So it is possible to construct expressions that violate the ruleset but are in fact convex. As an example consider the entropy function,\(-\sum_{i=1}^n x_i \log x_i\), defined for\(x>0\), whic...
