Cognitive Radio Performance Enhancement Based on Frequency Hopping System

Cognitive Radio (CR) is the technology of used free spectrum band based on the main element as the primary, secondary users, through the structure can sense the surrounding environment and adapt to the different operating parameters to enhance the communication quality. A flexible and adaptable physical layer implementation is needed to achieve a better enhancement cognitive radio system. In this paper, the proposed system based on the most beneficial spread spectrum technique based on the used parameters determined as the Frequency-hopping spread spectrum (FHSS) to attend the Physical layer requirements of Cognitive Radio. The used system based on the Throughput, Data Drop Rate, and Detection Time simulation parameters. The used method provides high throughput performance for CR implementation with simulation parameters used and sent/received data messages, So the number of data transmission without errors increased. Moreover, the proposed system has been done using OMNET++ simulation tool.
