Hybrid Spectrum Sensing: Status, Open Problem And Future Trends

Data transfer rates must be faster and more efficient as internet applications and wireless communications grow exponentially. As a result, a correct and effective spectrum is a must. As the demand for spectrum grows, the number of bands accessible to send and receive data decreases. One of the time-consuming duties is maximizing the utilization of these bands. Various spectrum sensing approaches come up with a literature review and elements of hybrid spectrum sensing techniques as well as several cognitive radio optimizations, are discussed in this article. The search will stop at several points, including challenges, status and Future Trend.
