The number of spatial streams can be no greater than the number of elements in the antenna array. When the count of array elements exceeds the number of spatial streams, there is an additional signal processing gain that can be used to improve the signal-to-noise ratio in beamforming. Beam...

解析 It is given that set A has 3 elements and the elements of set B are 3, 4,and 5.⇒ Number of elements in set B = 3Number of elements in (A × B)= (Number of elements in A) × (Number of elements in B)=3×3=9Thus, the number pf elements in (A × B) is 9....
Proof. Consider Z/(k), the ring of residues modulo k. The units group of Z/(k) is U(Z/(k)) which consists of the classes \bar x=x+(k) s.t. (x,k)=1. So the number of elements in U(Z/(k)) is \varphi(k). According to group theory, for every a\in U(Z/(k)), ...
