Proper allocation and utilization of spectrum by using cognitive radio networks: Bangladesh perspective

In recent years, spectrum scarcity is a major problem in wireless communication system which has been brought to a solution by using cognitive radio technology. This technology tends to increase the spectrum utilization. In this paper, an energy detection method has been proposed for proper utilization and allocation to the spectrum and also an overview of spectrum in Bangladesh. In real time system energy detection can be broadly used as a signal detection method for its lower complexity characteristics. Our scheme helps any channel distributor, by measuring the quantity of bandwidth that can be provided at any given time to any unlicensed user. From result we found that the output could be beneficial for the improvement of spectrum scarcity problem, save money and can develop our communication network system.
