Orthogonal complex spreading method for multichannel and apparatus thereof

摘要

An orthogonal compler spreading method for multiple channels allocating at least two input channels to first and second groups, comprising steps of:
generating a first output signal by multiplying (600) a first orthogonal sequence by first data and a first gain, outputting a first output;
generating a second output signal by multiplying (700) a second orthogonal sequence by a second data and a second gain; characterized by
generating a complex code by summing (810, 820) the first output signal and the second output signal in the complex form; and
complex-multiplying (900) the complex code by SC(OS3+jPOS4), wherein
SC is a spreading code, OS3 and OS4 are orthogonal sequences, and P is a predetermined sequence.
