Abstract  Abstract

An orthogonal complex spreading method for multiple data inputs each of the data inputs being allocated to either a first group or a second group comprising steps of:
generating first outputs (600) by multiplying each of data inputs in the first group (X 11 ... Xn1) by a corresponding orthogonal sequence and a corresponding gain respectively;
generating a first output signal (810) by summing the first outputs;
generating second outputs (700) by multiplying each of data inputs in the second group (X 12 ... Xn2) by a corresponding orthogonal sequence and a corresponding gain respectively;
generating a second output signal (820) by summing the second outputs;
receiving the first and second output signals in a complex form (900) and complex-multiplying the first and the second output signals by SC(OS 3+jP-OS4) (900 300) wherein SC is a spreading code OS3 and OS4 are orthogonal sequences and P is a predetermined sequence.
