“…According to Balian-Low Theorem [13], there is no way to utilize a well-localized prototype filter in both time and frequency, along with maintaining orthogonality and transmitting at the Nyquist rate. Hence, relaxing one condition guarantees the other two factors.…”

“…If the pulses employed at the transmitter and the receiver are the same, i.e., g(t) = γ (t), the approach is matched filtering [7]. Alternatively, different pulses can be used at the transmitter and the receiver, i.e., g(t) = γ (t), yielding the mis-matched filtering.…”

“…The condition (7) is also named as bi-orthogonality condition assuming g(t) = γ (t), since it is a prerequisite in bi-orthogonal division multiplexing (BFDM) systems for reconstructingã m,n from r(t) [6]. Under the condition that matched filtering is employed, i.e., g(t) = γ (t), (7) reduces to the orthogonality condition.…”

“…Recent 3GPP has conducted comprehensive discussions on waveform design for 5G new radio (NR). According to the latest agreements [3,4], orthogonal frequency-division multiplexing (OFDM)-and discrete Fourier transform spread OFDM (DFTs-OFDM)-based waveforms, including filtering and windowing for spectral containment, are the most promising candidates for 5G eMBB service, which is underpinned by In order to provide flexibility on physical layer, recent research has focused on enhancements of the OFDM waveform with respect to its supported numerologies and considering additional filtering components; for an overview, refer to [5][6][7]. Generally speaking, the new waveform proposals fall into two main categories: subcarrier-wise filtering, comprising filter bank multicarrier (FBMC) [6], windowed OFDM [8] and pulseshaped OFDM (P-OFDM) [9], etc, and sub-band wise filtering, composed of universal filtered (UF)-OFDM [10] and filtered OFDM [11], etc.…”

Spectrally contained OFDM-based waveforms are considered key enablers for a flexible air interface design to support a broad range of services and frequencies as envisaged for 5G mobile systems. By allowing for the flexible configuration of physical layer parameters in response to diverse requirements, these waveforms enable the in-band coexistence of different services. One candidate from this category of waveforms is pulse-shaped OFDM, which follows the idea of subcarrier filtering while fully maintaining the compatibility with CP-OFDM. In this paper, we provide an overview of pulse shaping methods in OFDM systems and propose a new pulse-shaped design method with arbitrary length constraint and good time-frequency localization property. Based on the pulse design, we discuss different receiver realizations and present a criterion for pulse shape evaluation. In addition, the parameterizations of OFDM system to address diverse requirements of the services envisaged for the 5G systems are described. Link and system performance results for selected scenarios show that a proper design of the OFDM numerologies and pulse shapes could substantially improve the performance under time and frequency distortions. Furthermore, pulse-shaped OFDM is able to support asynchronous transmissions and reduce the signal sensitivity to Doppler distortions, rendering it beneficial for various applications from the context of vehicular communications and the Internet-of-things.

“…The first proposal came from Chang in the 1960s, who presented the conditions required for signalling a parallel set of Pulse amplitude modulated (PAM) symbol sequences through a bank of overlapping vestigial side band (VSB) modulated filters [4]. Saltzberg extended the idea and showed how the Chang's method could be modified for transmission of Quadrature amplitude modulated (QAM) symbols [1]. In 1980s, Hiroshaki progressed more on FBMC and proposed an efficient polyphase implementation for the Saltzberg method [5].…”

: In recent years, filter bank multicarrier (FBMC) has recaptured widespread interests for its possible applications in cognitive radio and dynamic spectrum access. A distinctive feature for cognitive radio is its adaptivity to environment. When environment changes, a cognitive radio will change its parameters to optimize the transmission and receiving. Thus it is desirable to design a unified structure and algorithm for FBMC that needs little change for different parameters.In this paper, we propose a unified structure and parallel algorithms to implement the FBMC. The FBMC system and parallel algorithms are constructed based on the normalized prototype filter. The coefficients of the normalized prototype filter can be pre-computed and stored. The proposed parallel algorithms have the same structure for various choices of time duration, subcarrier spacing and bandwidth. Combined with known parallel algorithms for the fast Fourier transform (FFT), the proposed algorithms fully parallelize the computations for the transmitter and receiver, which can run much faster than conventional serial algorithms as modern processors usually have massive parallel capability. Keyword: FBMC,OQAM,FFT,WLAN,OFDM. I.INTRODUCTION Orthogonal frequency division multiplexing (OFDM) has been probably the most successful multi-carrier modulation (MCM) scheme for the wired or wireless communication in the past two decades and it is employed in the standard of today's 4G network. Meanwhile, OFDM still plays an important role in many current applications such as asymmetric digital subscriber line (ADSL), digital video broadcasting (DVB) and wireless local area networks (WLANs). However, with the increasing number of users and devices, the need for energy efficiency and sophisticated spectrum utilization at low costs drawbacks of OFDM become apparent such as the cyclic prefix (CP) leading to a decrease in the system efficiency. Consequently, other MCM methods have been proposed and evaluated recently and latest research indicates a great potential for these methods which may have a big influence on next generation communication systems and may replace the conventional OFDM. One important, new emerging MCM method is the filter bank based multicarrier FBMC) transmission, which introduces filter banks to the OFDM system and discards the CP. In this sense, the FBMC is an evolution of OFDM. The employed filter bank will import extract flexibility to the system to cope with some drawbacks of OFDM. Intuitively, the filter bank can be designed with different properties to satisfy the communication requirements. For example, for the OFDM system, CP is used to eliminate inter symbol interference (ISI). In order to remove this interference completely, the length of CP must be no shorter than the length of the impulse response of the corresponding channel. However, this CP-redundancy decreases both spectral and power efficiency. For the FBMC, instead of CP, filter banks can be designed and applied to reduce the out-of-band power leakage and inc...
