| Abstract | This paper investigates the transmitted waveform optimization issues for wideband Multiple Input Single Output (MISO) cognitive radio. For cognitive radio, a spectral mask for the transmitted waveform is determined on spectrum sensing, and arbitrary transmitted spectral shaping is required. Meanwhile, the interferences from primary radios should be canceled at the receiver of cognitive radio. The contribution of this paper is to optimize the MISO cognitive radio communication link by jointly considering the optimization objective, the spectral mask constraint at the transmitter and the interference cancellation at the receiver. Meanwhile, reduction in transmitted peak power and quantization is still very desirable, being concerned about implementation complexity and power consumption. These motive us to consider various practical constraints for waveform optimization in the context of MISO cognitive radio. A number of solutions are provided in this paper in conjunction with numerical results showing the optimal wideband waveforms. |

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.
