- M-QAM OFDM and PCC-OFDM Performance in the Presence of Phase Noise
- This paper addresses the issue of OFDM and PCC-OFDM systems impaired by phase noise PN. PCC-OFDM is a variation of OFDM in which data is mapped onto adjacent subcarrier pairs. As a result intercarrier interference ICI in adjacent subcarriers is cancelled. Phase noise in OFDM causes both ICI and common...

- Constant Envelope OFDM Phase Modulation: Spectral Containment, Signal Space Properties and Performance
- A class of constant envelope OFDM phase modulated (OFDM-PM) signals is studied. The motivation behind OFDM-PM is to alleviate the high peak-to-average power ratio of conventional OFDM systems. Power density spectrum plots and fractional out-of-band power curves are given. For small modulation indices, the OFDM-PM signals are shown to be...

- Design of Robust Pulses to Carrier Frequency Offset for OFDM/OQAM System
- The high sensitivity to carrier frequency offset of OFDM systems compared to single carrier systems is well known. This paper studies how this can be remedied for OFDM/OQAM systems by appropriate pulse shaping. Building on earlier methods for minimizing out-of-band energy, a procedure for pulse shape design is derived. The...

- Multisubchannel Detection Techniques for Mobile OFDM Systems
- One of the critical problems of mobile OFDM systems is the loss of the subchannels' orthogonality, if the channel impulse response changes during one OFDM block. OFDM systems experience intersubchannel interference in mobile receivers if the channel impulse response changes significantly during one OFDM block. This paper presents the mathematical...
