| Abstract | Blind separating the intercepted signals is a research topic of high importance for both military and civilian communication systems. A blind separation algorithm suitable for Multiple Input Multiple Output (MIMO) systems in association with Space-Time Block Code (STBC) has been reported in literature by utilizing Independent Component Analysis (ICA). This algorithm can not deal with complex phase-shift keying (PSK) modulated signals since the real and imaginary parts are not mutually independent. In this paper, an extending algorithm is proposed by applying a rotation transform to maximize the independence between the real and imaginary parts without using a precoder (rotation) at the transmitter side. Simulations show that the new algorithm can separate complex PSK-modulated signals blindly with high Symbol Error Rate (SER) performance when Channel State Information (CSI) and coding matrix are unavailable. |

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.
