    摘要： An orthogonal complex spreading method for a multichannel and an apparatus thereof are disclosed. The method includes the steps of complex-summing &agr;n1WM,n1Xn1 which is obtained by multiplying an orthogonal Hadamard sequence WM,n1 by a first data Xn1 of a n-th block and &agr;n2WM,n2Xn2 which is obtained by multiplying an orthogonal Hadamard sequence W1,n2 by a second data Xn2 of a n-th block; complex-multiplying &agr;n1WM,n1Xn1+j&agr;n2WM,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： Generally, Reed-Solomon encoding process in the conventional communication system is executed by a Reed-Solomon encoder having different code rates for different data transmission rates. The present invention does not use a Reed-Solomon encoder having different coding rates, but instead uses a Reed-Solomon encoder having the same code rate regardless of data transmission rate. Accordingly, the present invention has the following effects. The present invention maintains same communication quality regarding data services having each different data transmission rate, and can use a single Reed-Solomon encoder.
