Performance Comparison between OQAM and N-continuous OFDM
نویسندگان
چکیده
Orthogonal frequency division multiplex/offset QAM (OFDM/OQAM) and N-continuous OFDM are both improved multi-carrier modulation (MCM) techniques for the transmission of signals over multipath fading channels. In this paper, we aim to compare these two techniques with respect to out-of-band radiation, bit error ratio (BER) and calculation complexity. Analysis and simulation results show that, compared to the N-continuous OFDM, the OFDM/OQAM has lower out-of-band radiation, calculation consumption and similar BER performance.

Performance Comparison of CP-OFDM and OQAM-OFDM Based WiFi Systems
In this contribution, a direct comparison of the Offset-QAM-OFDM (OQAM-OFDM) and the Cyclic Prefix OFDM (CP-OFDM) scheme is given for an 802.11a based system. Therefore, the chosen algorithms and choices of design are described and evaluated as a whole system in terms of bit and frame error rate (BER/FER) performance as well as spectral efficiency and complexity in the presence of multipath pro...
متن کاملComparison between MC-CDMA and CDMA- OFDM/OQAM systems in presence of MIMO channel
In this paper, we present a comparison between MCCDMA and CDMA-OFDM/OQAM systems in the case of MIMO channel. The advanced Multi Carrier CDMA OFDM/OQAM modulation is a combination of CDMA and OFDM/OQAM. This combination takes advantages from multicarrier modulation and spread spectrum. Indeed, the use of OFDM has proved its ability to fight against frequency selective channels but the insertion...

متن کاملHS-OQAM PLC: Long Filter or Equalizer?
This paper addresses a theoretical analysis on OFDM/OQAM based transmission in PLC. We reveal that inter-carrier interference (ICI) may be a predominant factor to limit the performance comparing with inter-symbol interference (ISI) when the channel has frequency selective behavior. Thus, for the filter design task, more attentions should be paid on its stopband energy than on orthogonality cond...
