| Abstract | The evaluation of signal detection algorithm involves two aspects: computational complexity and performance. Based on the statistical covariances of the signal, the well-known spectrum sensing algorithm named as maximum-to-minimum ratio eigenvalue (MME) algorithm was proposed in [1]. MME is a blind signal detection algorithm and it has good performance. The main advantage of MME is that it does not related to the noise power. However, due to involving eigenvalue decomposition, MME has a high computational complexity. MME is not the best signal detection algorithm based on statistical covariance matrix. Therefore there may be other algorithm can perform better than MME. In this paper, based on the idea of the approximation of the eigenvalue of the matrix, we proposed three spectrum sensing algorithms with lower complexity. These algorithms are also blind spectrum sensing algorithms, and they are not sensitive to the noise power. Simulation results demonstrate that their performances are better than that of the MME algorithm. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
