Abstract

The tremendous growth of wireless digital communications and additive use of users has raised spectrum shortage and security issues in the last decade. The main obstacle for the growth of wireless digital communications is the fixed spectrum allocation and non-availability of new bands in the spectrum. For sharing the fixed spectrum allocation it makes spectrum inflexible. The inefficient utilization of spectrum bands was the result of pre-allocation of spectrum bands. The spectrum scarcity is not the real problem whereas inefficient spectrum allocation and its usage lead to the scarcity. For network implementation, Cognitive radio or Intellectual radio is believed to be the key enabling technology. Recent spectrum sensing algorithm-binary hypothesis detecting model was reviewed in this paper.
