Abstract

In the recent past, the Cognitive Radio Network (CRN) plays significant role in mobile technology for energy efficient wireless 5G communication. The Non Orthogonal Frequency Multiple (NOMA) communication technology is applied for energy efficient CRN wireless communication. The CRN is an important research area for 5G wireless communication that permit unlicensed Secondary Users (SU) to access the spectrum by achieving energy efficiency. The energy efficiency of SU can be optimized by providing Carrier Frequency Offset (CFO) synchronization and Peak Average Power Ratio (PAPR) minimization in a cooperative spectrum sensing of the CRN. The major issue in CRN is synchronization and error during the transmission and reception of input data. In this research, the synchronization and error correction techniques are proposed to improve the energy efficiency of CRN for improving 5G wireless communication. A novel algorithm is proposed for CFO synchronization and PAPR minimization. The quick calculation of synchronization variable plays an enormously significant part in the modulation and demodulation of CRN data. The novel algorithm is used to provide optimal solution in high computational complexity for various synchronization parameters such as CFO, timing error and PAPR by applying Offset Quadrature Amplitude Modulation (OQAM). The NOMA technology is incorporated for transmitting data by the SU with OQAM modulation. The experimental results prove that proposed methodology attains energy efficiency by improving synchronization and minimizing errors.
