In this paper we discuss the synchronization problems in cognitive radio systems and suggested an efficient synchronization aspect. For this type of system the secondarytransmitter is well aware of the transmission timing of the primary transmitter forbetter harmonizing in the primary and secondary system. We also discuss the time and frequency aspects of the system. For analysis we split the transmission spectral efficiency in two parts from reducing the time delay and improving the efficiency.We estimate the delay in the synchronization and equalization mode by using Matlab for programming and simulation.

Cognitive Radio, synchronization, equalization, time delay.
