    摘要： An orthogonal complex spreading method for a multichannel and an apparatus thereof are disclosed. The method includes the steps of complex-summing αn1WM,n1Xn1 which is obtained by multiplying an orthogonal Hadamard sequence WM,n1 by a first data Xn1 of a n-th block and αn2WM,n2Xn2 which is obtained by multiplying an orthogonal Hadamard sequence W1,n2 by a second data Xn2 of a n-th block; complex-multiplying αn1WM,n1Xn1+jαn2WM,n2Xn2 which is summed in the complex type and WM,n3+jPWM,n4 of the complex type using a complex multiplier and outputting as an in-phase information and quadrature phase information; and summing only in-phase information outputted from a plurality of blocks and only quadrature phase information outputted therefrom and spreading the same using a spreading code.

    摘要： The present invention relates to a ventilator, aiming easier cleanup even in the position mounted on the ceiling or wall. According to the present invention, a ventilator may comprise an outer casing having a mounting space in an inside thereof, an inner casing mounted in the mounting space of the outer casing, a blowing fan received in an inner space of the inner casing, and a motor rotating the blowing fan, wherein a wave-shaped flow path is formed on each inner wall surface of the inner casing.
