Peak-to-Average Power Ratio Reduction of OFDM Signals Using Pulse Shaping

This paper proposes an efficient technique for reducing the PAPR of OFDM signals. The proposed technique is very effective and avoids the use of extra Inverse Fast Fourier Transformations IFFTs as was done in some previously published techniques but instead is based on a proper selection of the time-limited waveforms...

Performance Degradation of OFDM and MC-CDMA to Carrier Phase Jitter

This paper analyses the effect of carrier phase jitter on the performance of OFDM and MC-CDMA waveforms. Assuming a multicarrier downlink through an AWGN channel, this paper investigates the impact of jitter phase models on the SNR degradation. This paper proposes to consider a small random process, a gaussian process...
