摘要
The present invention is a novel and improved method and apparatus for reducing peak to average ratio in a system using auxiliary pilot channels as described in the TIA/EIA TR45.5 "cdma2000 ITU-R RTT Candidate Submission" to the ITU for consideration in the third generation wireless communication systems. A first method proposed in the present invention to deal with the above stated problem is to alter the phase of the auxiliary pilot channels to reduce to prevent the auxiliary pilot channels from adding constructively. A second method proposed in the present invention to deal with the above stated problem is to gate out the portion of the auxiliary pilot channels that add constructively. The present invention also proposes a novel demodulator design for receiving signals using the modified auxiliary pilot signals.
