  • OFDM modulation using a shaping filter
    Patent number: 8090037
    Abstract: Reducing peak-to-average power ratio (“PAPR”) for modulation and demodulation is described. Complex sample values are obtained in a time domain for orthogonal frequency division multiplexed (“OFDM”) signaling. The complex sample values are transformed into a frequency domain. The set of spectral samples is multiplied with a filter spectrum to shape the set of spectral samples to provide spectral products.
