This paper presents a contextual literature review of the different approaches with their simulation results and identifies the one that best suits the cognitive radio environment. In recent years, a variety of transmit power control algorithms have been proposed for organizing cognitive radio networks. Firstly, we review the two transmit-power control schemes, which are specified in existing research papers, namely fixed and adaptive transmit-power control schemes. Secondly, we proposed transmit-power control schemes based on spectrum sensing side information. In order to achieve better sensing performance, we are employing more number of antennas at secondary user. Due to better sensing performance, we can exercise more accurate control on transmit power of secondary user transmitter
