Abstract: Technologies are generally provided to enable the peak-to-average power ratio (PAPR) in OFDM communication systems to be adjusted to a particular level. In some examples, an N-symbol transmission vector may be partitioned into k equal partitions, a Fast Fourier Transform (FFT) may be performed on each partition, and an interleaving union of FFT results may be generated. The results of the interleaving union may be used for transmission after mapping them to the M subcarriers and performing an M-point IFFT. On the receiver side, FFT may be performed on M subcarriers, where each of L end user devices may be assigned N subcarriers out of M=N*L available subcarriers. The N subcarriers of the FFT results may be de-mapped and subjected to an interleaving partition. Subsequently, an Inverse FFT (IFFT) may be performed on each partition and results of the IFFT operation employed for symbol detection.
