The invention relates generally to a multi-unit cosmetic applicator comprising a housing body, a first cosmetic unit housed in the housing body, a second cosmetic unit housed in the housing body, an opening in the housing, wherein each cosmetic unit has a means for being independently movable relative to each other from a stored position to an advanced position and back to its stored position. The insulative housing includes first and second mating segments side by side arranged along a lateral direction perpendicular to a mating direction and divided by a partition wall, and a rear wall extending downwardly from rear ends of the first and second mating segments and forming a division section to divide the rear wall into two parts corresponding to the first and second mating segments. The terminal may also calculate channel direction information and channel quality information in a per user unitary rate control mode by reusing the channel direction information and the channel quality information in the zero-forcing mode.
