European Journal of Electrical Engineering and Computer Science, 2022
Higher data rates, higher mobility, lower latency, and better quality of service are the prime requirements for future communication systems. It is expected to provide connectivity to the Internet of everything, time-sensitive/time-engineered application, and service to high-fidelity holographic society. Its performance in terms of data rate, latency, synchronization, security, and reliability will be much better compared to 4G and 5G mobile communication systems. This paper investigates the performance of the pulse shaping-based filter bank multicarrier (FBMC) modulation technique used in 5G mobile communication systems. Simulation results show that the FBMC system has a better performance compared to the conventional orthogonal frequency division multiplexing (OFDM) system in terms of many parameters such as achievable channel capacity, signal to noise ratio, time, and frequency response, out of band leakage, etc.
Filter Banks for Next Generation Multicarrier Wireless Communications
EURASIP Journal on Advances in Signal Processing, 2010
The theoretical capacity limits in communications can be approached by multicarrier techniques. With radio channels, multicarrier techniques can be combined with multiantenna transmitters and receivers to provide efficiency. Existing or planned transmission systems rely on the OFDM technique to reach these goals and a considerable amount of research has been devoted to these techniques during the last 20 years. However OFDM has a number of drawbacks, such as the use of the cyclic prefix to cope with the channel impulse response which results in a loss of capacity and the requirement of block processing to maintain orthogonality among all the subcarriers. Furthermore, the leakage among frequency subbands has a serious impact on the performance of FFT-based spectrum sensing and OFDM-based cognitive radio in general.

A wireless communication is looking for higher bandwidth with greater spectral efficiency. Multicarrier communication technology has been suggested as a suitable candidate to utilize the white spaces in the spectrum. OFDM was the first multicarrier technique proposed for 4G (LTE-A) and has been successfully deployed in 4G systems. But due to the use of cyclic prefix and the high PAPR the OFDM communication system cannot be suitable for 5Gs. This paper discusses how FBMC can be designed and proves that it is the most efficient waveform selection for next generation wireless communication i.e. 5G communication system.

Filter Bank Multicarrier for Massive MIMO
2014 IEEE 80th Vehicular Technology Conference (VTC2014-Fall), 2014
This paper introduces filter bank multicarrier (FBMC) as a potential candidate in the application of massive MIMO communication. It also points out the advantages of FBMC over OFDM (orthogonal frequency division multiplexing) in the application of massive MIMO. The absence of cyclic prefix in FBMC increases the bandwidth efficiency. In addition, FBMC allows carrier aggregation straightforwardly. Self-equalization, a property of FBMC in massive MIMO that is introduced in this paper, has the impact of reducing (i) complexity; (ii) sensitivity to carrier frequency offset (CFO); (iii) peak-to-average power ratio (PAPR); (iv) system latency; and (v) increasing bandwidth efficiency. The numerical results that corroborate these claims are presented.
Channel Equalization in Filter Bank Based Multicarrier Modulation for Wireless Communications
EURASIP Journal on Advances in Signal Processing, 2007
Channel equalization in filter bank based multicarrier (FBMC) modulation is addressed. We utilize an efficient oversampled filter bank concept with 2x-oversampled subcarrier signals that can be equalized independently of each other. Due to Nyquist pulse shaping, consecutive symbol waveforms overlap in time, which calls for special means for equalization. Two alternative linear low-complexity subcarrier equalizer structures are developed together with straightforward channel estimation-based methods to calculate the equalizer coefficients using pointwise equalization within each subband (in a frequency-sampled manner). A novel structure, consisting of a linear-phase FIR amplitude equalizer and an allpass filter as phase equalizer, is found to provide enhanced robustness to timing estimation errors. This allows the receiver to be operated without time synchronization before the filter bank. The coded error-rate performance of FBMC with the studied equalization scheme is compared to a cyclic prefix OFDM reference in wireless mobile channel conditions, taking into account issues like spectral regrowth with practical nonlinear transmitters and sensitivity to frequency offsets. It is further emphasized that FBMC provides flexible means for high-quality frequency selective filtering in the receiver to suppress strong interfering spectral components within or close to the used frequency band.

Electronic Government, an International Journal, 2017
As the world, is looking for more data speeds along with support for M2M communication in the next generation (5G), the current orthogonal frequency division multiplexing (OFDM) has limitations such as high PAPR, spectrum wastage due to cyclic prefix (CP), out of band (OOB) emissions. To overcome these limitations, 5G researchers is looking for different wave forms and filter bank multi carrier (FBMC) waveform is one of the prime contenders. In this paper, it has been implemented, the poly-phase network filter bank multi carrier (PPN-FBMC), which reduces the high complexity and computations. A prototype filter for the PPN FBMC with high overlapping factors (K = 6 and 8) are implemented. It also simulates FBMC system using Matlab Software, to characterise and analyse the 5G candidate waveform FBMC and compare with OFDM, in terms of error vector magnitude (EVM), peak to average power ratio (PAR), and power spectral density (PSD) performance. The simulated results prove that FBMC outperforms the OFDM systems in all the above mentioned aspects, even under noisy conditions.

OFDM is an incredible Multiple Access Modulation strategy adopted in Fourth Generation (4G) communication system even though it is not exempt of defects. OFDM suffers from the difficulty of Side band leakage. To overcome this, FBMC modulation scheme is used. This paper gives an overview of dominant metrics like Power Spectral Density (PSD), Bit Error Rate (BER) of forthcoming Cellular Communication System's modulation scheme. The simulation results of FBMC under perfect channel assumption gives BER values of 0.010213, 0.009945 for K=3, 4 respectively at a Signal to Noise Ratio (SNR) of 5dB. It is also observed that the effect of Rayleigh and Rician channels in FBMC give BER values of 0.49988, 0.5081 and 0.15615, 0.12549 for K=3, 4 respectively. From the simulation results it is observed that, FBMC outperforms the most popularity gained by 4G modulation technique.
