Abstract

The recent research on communication systems has found that, because of its high spectral efficiency, multicarrier (MC) techniques are more desirable for the development of modern wired or wireless communication systems. So far, the most common modulation technique in 4th (4 G) and Long-term Evolution (LTE) systems is orthogonal frequency multiplexing (OFDM). The low frequency range of subcontractors within OFDM systems, given its various advantages, limit the applicability of some present and future communications systems such as Cognitive radio (CR) and Dynamic spectrum access (DSA). Multicarrier Filster Bank (FBMC) is an revolutionary OFDM technology that solves most of the problems by using a multi-carrier communication network filtering approach. FBMC signals easily follow the CLAR and do not use the cyclic prefix to increase spectral efficiency. The transmission method Filter Bank Multicarrier (FBMC) contributes to improved physical layers for future communication networks and is a cognitive radio-based technology. Multimedia data services demand has risen rapidly in the recent past. Orthogonal Frequency Division Multiplexing (OFDM) is one of the most promising multi-carrier technologies for all 5 G wireless communication networks due to its high power, high data rate and universal coverage with high mobility. The peak-to-average power ratio (PAPR) is significantly influenced by OFDM. Unfortunately, with the high PAPR intrinsic to OFDM signals, high-power amplifiers (HPAs) are often worked on its characteristic curve in the nonlinear region. The key emphasis of this paper is the MIMO-OFDM network PAPR reductions by partial transmission sequences (PTS) and precoding methods. Other methods like the clipping of amplitude have little difficulty. On the other hand, they have issues such as distortion of the in-band and expansion of outside-band. The methods of signal compounding have low complexity, strong distortion and spectral properties but restricted potential for PAPR decrease.
