| Abstract | A coding scheme for concatenation space-time codes to achieve the maximum diversity over the time-selective block Rayleigh fading channels via the time-frequency duality is proposed in this paper. Based on the basis expansion model (BEM) for the time-selective fading channels, we firstly inversely convert it into the corresponding virtual frequency-selective fading circulant matrix by pre- and post-multiplying IFFT and FFT matrix in the transmit and receive end respectively. And then with OFDM module, general space-time codes can be directly applied in it. Based on the pairwise error probability (PEP) analysis in case of rapid fading, we derive design and performance criteria for the concatenation space-time block coding. Extending the full diversity space-frequency coding approach proposed previously to our consideration, we construct the space-time-Doppler block codes from the general space-time codes through repetition, which achieve the maximum additional Doppler diversity besides space and time diversity. Simulation results demonstrate the excellent performance of the proposed technique |

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.
