COGNITIVE RADIO NETWORK 3Introduction The cognitive radio can be considered as a wireless communication system in which atransceiver can intelligently detect which communication channel are in use and which arenot in use. This can help in moving to a free channel avoiding the occupied one (Han, Dianatiand Nekovee2016). The concept mainly optimizes the use of the radio frequency which isavailable while concern to interference which is related to others. Considering the basic form,the cognitive radio is a technology which is hybrid which involves software defined radio asapplied to the spread spectrum communication. The possible function of the cognitive radiomainly includes the foremost ability to transceiver to determine the geographic location,identify and the user authorization, decrypt and encrypt signals, sense wireless neighbouringdevices in the operation and the adjustment of the power output and the characteristics of themodulation.The main aim of the report is put emphasis on the channel allocation problem. Takinginto account the concept of how to allocate a single Dynamic Channel Allocations channelamong the users who are competitive. The problem which is related with the techniques isalso taken into consideration and comparison between the fixed channel allocation and thedynamic channel allocation is put forward.Allocation schemeThere are mainly two types of allocation process fixed channel allocation andDynamic channel allocation.Fixed channel allocationThis allocation technique can be done using the static multiplexing method which areFDM and TDM (Frequency / time division Multiplexing). The frequency division
