METHODS AND APPARATUS FOR ENCODING AND DECODING DATA

摘要

A method for encoding data is presented, comprising the steps of: generating a respective data signal for each of a plurality of users; coding each of the data signals with a respective orthogonal spreading code to produce respective encoded data signals; and summing the encoded data signals to produce a total encoded data signal. The method further comprises the step of applying a phase shift to one of the data signal, the encoded data signal and the total encoded data signal.
