“…The obtained results are tabulated in Table II. Note that in general the sub-optimum SEP has the smallest error rates, for different roll-off factors and timing offsets, compared to the RC, the pulses proposed in [8] (r(t), q(t), and v(t)), the PFE [11], as well as the IPLCP. This behaviour is consistent with the wider eye opening of the SEP.…”

“…In the expression g k = p (kT + η), p(t) is the ISI-free pulse evaluated. The parameters used to make the truncated Fourier series converge comply with the parameters used in previously reported manuscripts [3], [4], [8], [11]. These parameters are given in Table I.…”

“…The families of Nyquist-I pulses proposed in [8] (r(t), q(t), and v(t)) are one of the newest families of pulses found in the literature. Further, the recently proposed PFE [11] is also evaluated, as well as the improved parametric linear combination pulse (IPLCP) [3], and the sinc parametric linear combination pulse (SPLCP) [4].…”

“…Other ISIfree linear combination pulses have also been proposed in [2] and [9]. A novel family of ISI-free pulses with senary piecewise polynomial frequency characteristic is proposed in [10], whereas in [11] a new parametric family of Nyquist ISI-free pulses was proposed, denoted as piecewise flipped-exponential (PFE) pulse. All of the previous families of ISI-free pulses are characterized by having additional variables to the roll-off factor; therefore, adding supplementary degrees of freedom in the design.…”

In this manuscript, the sinc exponential pulse (SEP) is evaluated at the transmitter and receiver side by using different metrics. The impulse response of the SEP is derived, analysed, and compared with the traditional RC pulse. The SEP is characterized by introducing two new design parameters, adding degrees of freedom to optimize the pulse for a certain transmission scheme and roll-off factor. The SEP is optimized via numerical simulations to diminish the bit error rate (BER) in the presence of symbol timing errors. Eye diagrams are used to visually evaluate the sensitivity of the communication system due to intersymbol interference (ISI). In general, the SEP outperforms other existing pulses in terms of BER, evaluated for different symbol timing-errors and roll-off factors.

“…The lower side lobes of the filters made the system less affected to ISI and Inter Carrier Interference (ICI). The authors in (Alexandru & Balan, 2016) demonstrated that with Piecewise Flipped Exponential (PFE) pulses, better BER performances are obtained. In (Mohammad, Abdelhamid, & Hafez, 2015), New Nyquist Linear Combination Pulse (NNLCP) which effectively controlled high peak to average power ratio (PAPR) of IFDMA while keeping the same bandwidth compared to Raised Cosine (RC) was presented.…”

The most commonly used multicarrier modulation method in 802.11 wireless communication systems is Orthogonal Frequency Division Multiplexing (OFDM). However, OFDM is easily affected by Inter Symbol Interference (ISI). In this paper, different pulse shaping filters are employed in the OFDM system and three new filters are presented to further reduce ISI effects. The first one is a Modified Parametric Exponential Pulse (MPEXP) filter which employs a different transfer function that is implemented at the transmitter side. The second one is a Better Than Modified Flipped Exponential Pulse (BTMFEXP) filter which is derived by modifying the transfer function of Modified Flipped Exponential Pulse (MFEXP). The third one is a hybrid of BTMFEXP and MPEXP (HBTMFPEXP). Lastly, low complexity forms of the MFEXP and BTMFEXP, derived from Taylor Series, are implemented. The OFDM system was tested with the existing and proposed pulses over AWGN and Fading channels. The proposed filters show better Bit Error Rate (BER) performance. Under a high ISI level, BTMFEXP and HBTMFPEXP showed a gain of 0.23 and 0.57 dB respectively over MFEXP with AWGN channel. With a fading channel at high ISI level, the proposed BTMFEXP and HBTMFPEXP demonstrated a gain of 2.33 and 5.33 dB respectively over MFEXP. ARTICLE HISTORY
