A peak-to-average power reduction method for third generation CDMA reverse links

Proposals for third generation cellular standards based on code division multiple access (CDMA) methods are being developed in several standards bodies around the world. The reverse link (mobile-to-base station) in these proposals is similar in structure and function. A method is described that redu...

Description
Summary:Proposals for third generation cellular standards based on code division multiple access (CDMA) methods are being developed in several standards bodies around the world. The reverse link (mobile-to-base station) in these proposals is similar in structure and function. A method is described that reduces the peak-to-average power of the mobile station transmission. By reducing the peak-to-average power ratio, spectral regrowth created by the mobile station power amplifier is reduced. This method is known as hybrid PSK (HPSK). HPSK is utilized in the generation of the complex scrambling sequence of the reverse link. Currently, HPSK has been adopted for the reverse link of third generation CDMA proposals by the TIA for the USA, ETSI for Europe, ARIB for Japan, and TTA for Korea.
