Design of Robust Pulses to Carrier Frequency Offset for OFDM/OQAM System
Overview 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 new pulses are optimal with respect to interference in OFDM/OQAM systems. It is also demonstrated that, in this respect, OFDM/OQAM outperforms OFDM/QAM systems using rectangular pulses.
