Abstract:
An apparatus and method for processing a constant amplitude sequence yields a transmission signal exhibiting a low PAPR. The method comprises extending a constant amplitude sequence, such as a Zadoff-Chu sequence, by adding to the sequence one or more complex-valued elements that have the same amplitude as other complex-valued elements in the sequence. The method also includes upsampling the extended sequence by linearly interpolating a difference in phase between adjacent complex-valued elements in the extended sequence. The method further entails limiting a bandwidth of the upsampled sequence by low pass filtering the upsampled sequence. The method may also include transmitting the band limited sequence. Due to the low PAPR of the transmitted signal, a power amplifier, which may be integrated with other circuits in a System-on-Chip, may have a low backoff. This yields high efficiency for the amplifier, hence low power consumption, and extended battery life in radio network devices.

Claim (Index 58):
The method of  claim 57 , wherein the node is a network node, and wherein the method is further characterized by sending the band limited sequence to a base station for transmission as a synchronization signal.
