摘要： A method of wirelessly transmitting digital signal includes the steps of (a) dividing a digital signal into a primary signal band and a secondary signal band; (b) phrase-shifting the secondary signal to form a reverse signal with respect to the primary signal band in such a manner that the reverse signal is one hundred and eighty degrees out of phrase with the primary signal band; (c) encoding the primary signal band and the reverse signal; (d) wirelessly transmitting the primary signal band and the reverse signal; (e) decoding the encoded primary signal band and the encoded reverse signal; and (f) combining the primary signal band and the reverse signal to re-form the digital signal.
