| Abstract | We consider a layered space-frequency (LSF) extension to bit-interleaved coded modulation (BICM) for MIMO-OFDM systems. We derive tight analytical bounds for the coded BER when using zero-forcing (ZF) detectors. The analysis does not rely on standard BICM expurgation techniques, and provides exact expressions for the codeword pairwise error probability at high SNR. We show that the LSF extension achieves the same diversity order as non-layered systems, while also achieving significant cant SNR gains when the number of transmit antennas is large. We quantify the SNR gain and show that it is a function of the antenna configuration only, and is independent of the modulation and coding parameters. We also present simulation results for MIMO extensions to IEEE 802.11a OFDM WLANs |

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.
