“…Various schemes to reduce the peak-to-average power ratio (PAPR) and ICI have been introduced in the literature. These schemes consist of the improved modified Bartlett-Hanning pulse [46], [47] and the improved parametric linear combination pulse (IPLCP) [48], [49], to improve the OFDM system error performance and reduce the ICI.…”

Cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) is the most widespread multicarrier modulation scheme. However, the use of a rectangular filter in CP-OFDM causes poor outof-band (OoB) radiation. Moreover, the CP causes spectral efficiency loss. To overcome these limitations, a filter bank multicarrier (FBMC) was proposed which uses prototype pulse shaping filters that can be adapted to fulfil the system requirements. The choice of the filter is crucial for FBMC/offset quadrature amplitude modulation (OQAM) due to its significant impact on the achieved performance. In this paper, new prototype pulse shaping filters in FBMC/OQAM systems are proposed, aiming to improve the system performance. A number of prototype pulse shaping filters, such as raised cosine pulse (RC), root raised cosine pulse (RRC), better than raised cosine pulse (BTRC), modified Bartlett-Hanning (MBH), improved sinc power pulse (ISP), phase modified sinc pulse (PMSP), parametric linear pulse (PLP), linear combination pulse (LCP), PHYDYAS and Hermite, are considered. The performance of each pulse shaping filter in FBMC/OQAM is evaluated and compared other in terms of the power spectral density (PSD), spectral efficiency, signal-to-interference ratio (SIR), time offset (TO), carrier frequency offset (CFO) and bit error rate (BER) performance over various channels. In addition, as multiple input multiple output (MIMO) is one of the main challenges associated with FBMC, we propose the new approach that use the frequency/time block spreading based on a Walsh-Hadamard (WH) code in MIMO FBMC/OQAM and investigate the combination of the our proposed prototype pulse shaping filters with MIMO systems. The proposed filters are shown to be suitable candidates for FBMC/OQAM systems.

“…It is shown in literature that Alexandru and Onofrei (2010), Kumbasar and Kucur (2007) and Mourad (2007) outperform all previously reported work, and therefore we have compared our proposed windowing function with sinc pulse (SP) (Mourad, 2007), improved sinc pulse (ISP) (Kumbasar & Kucur, 2007) and phased modified sinc pulse (SM) (Alexandru & Onofrei, 2010) only. The paper also includes the peak to average power ratio (PAPR) (Müller, Bäuml, Fischer, & Huber, 1997;Ochiai & Imai, 2001;Saxena & Joshi, 2013) comparison analysis of the proposed window with the existing methods in literature.…”

A new transmitter side windowing function to reduce inter-carrier interference (ICI) in orthogonal frequency division multiplexing (OFDM) systems with carrier frequency offset is proposed in this paper. The results show that the proposed method outperforms all the recently proposed windowing functions in the literature in terms of average signal power to average ICI power ratio (SIR), bit error rate (BER) and peak to average power ratio (PAPR).
