Single carrier transmission with frequency domain equalization (SC/FDE) system with a PAPR Of unity

The objective of this work is to eliminate the problems associated with the peak to average power ratio (PAPR) of the single carrier transmission with frequency domain equalization (SC/FDE) system. This could be achieved by adapting the constant envelope type modulation (continuous phase modulation CPM), which, by nature, normalizes the PAPR for the SC/FDE. Ultimately, a comprehensive treatment of the problems of the PAPR is obtained. The central question always is whether the constant envelope modulation scheme suits the block-wise transmission, which is required for SC/FDE. Also, the adaption preserves the phase continuity of the constant envelope signals.
