Orthogonal Frequency Division Multiplexing with Offset Quadrature Amplitude Modulation (OFDM/OQAM) is a multicarrier modulation scheme that can be considered as an alternative to the conventional Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) for transmission over multipath fading channels. In this paper, we investigate the combination of the OFDM/OQAM with Multiple I...

Orthogonal Frequency Division Multiplexing (OFDM) faces the Peak-to-Average Power Ratio (PAPR) problem that is a main disadvantage in multicarrier transmission system.

Generalized frequency division multiplexing (GFDM), windowed cyclic prefix circular offset quadrature amplitude modulation (WCP-COQAM) and orthogonal frequency division multiplexing (OFDM) are among the candidate 5G modulation formats. In this study, we present additional results for the OOBE comparisons between OFDM, GFDM and WCP-COQAM under equal or unequal spectral efficiency conditions for ...

Presently, digital signal process strategies are wide studied and varied DSP primarily based schemes are appointive for next-generation passive optical network (PON).

Orthogonal frequency division multiplexing (OFDM) is a method of encoding digital data over a multiple carrier frequencies. OFDM stands for Orthogonal Frequency Division Multiplexing and also it is a modulation technique for transmitting large amounts of digital data over a radio wave. OFDM for wireless communications is used for PAPR reduction techniques. KeywordsOFDM, Peak-Average-Power Ratio...

In-band full-duplex transmission allows a relay station to theoretically double its spectral efficiency by simultaneously receiving and transmitting in the same frequency band, when compared to the traditional half-duplex or outof-band full-duplex counterpart. Consequently, the induced self-interference suffered by the relay may reach considerable levels of power, which decreases the signal-to-...

Orthogonal frequency division multiplexing (OFDM) combined with time division multiplexing (TDM), called OFDM/TDM, can overcome the high peak-to-average-power ratio (PAPR) problem of the conventional OFDM. Its bit error rate (BER) performance in a frequency-selective fading channel is improved by adoption of frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion...

Orthogonal Frequency Division Multiplexing(OFDM) is a method in which modulation of signal is done. Orthogonal Frequency Division Multiplexing has become popular technique for transporting large amount of data in both wired and wireless communication. It is a digital modulation technique in which signal is transmitted in parallel mode. As compared to single carrier system OFDM is more unaffecte...

Orthogonal Frequency Division Multiplexing (OFDM) is a well-known technique for the broadband wireless communication system. However, a main problem in OFDM is its vulnerability to frequency offset errors due to which the orthogonality is destroyed that result in Inter carrier Interference (ICI). ICI causes power leakage among subcarriers thus degrading the system performance. This paper studie...

Orthogonal frequency division multiplexing has drawn explosive attention as a new type of high data rate transmission scheme for wireless communication system. The main advantage of OFDM system are spectral bandwidth efficiency and robustness against frequency selective fading or narrowband interference etc. However a critical drawback of OFDM is high peak-to-average-power ratio (PAPR), which r...
