Improved Alamouti STBC Multi-Antenna System Using Hadamard Matrices

引用

International Journal of Communications, Network and System Sciences 2014年第3期7卷 83-89页

To achieve multiple input multiple output (MIMO) in wireless communication, the orthogonal space-time block coding (OSTBC) is evaluated next. At first, the OSTBC design is extended to include Hadamard matrix, referred to in this work, as traditional Hadamard OSTBC. Next, the Hadamard matrix is imposed on the conventional OSTBC, which is referred to, in this work as, Alamouti-Hadamard STBC. Both the traditional Hadamard OSTBC and the conventional STBC are compared with the Alamouti-Hadamard STBC. It will be shown that imposing the Hadamard conditions over the conventional OSTBC, the performance of the OSTBC 2-transmit antenna scheme can be significantly improved in terms of ber performance. All propositions are well supported with analytical derivations.

This is a multidimensional review of mangrove fungi occurring as saprobes,pathogens and endophytes of a wide range of host substrates and those isolated from the water columns and sediments in ***-hundred and fifty taxa including 658 that are supported by both morphology and molecular data and 192 with only morphological data are *** constitute Ascomycota,the dominant group with 773 species,and 58 Basidiomycota,one Blastocladiomycota,five Chytridiomycota,and 13 *** study also includes data on mangrove yeasts 103 Ascomycota,39 Basidi-omycota and 193 taxa isolated from *** isolated from submerged parts of mangrove plants total *** most specious orders of mangrove fungi are Pleosporales 133,Saccharomycetales 102,Microascales 101,Eurotiales 87,Hypocreales 60 and Xylariales *** genera include Candida 39,Aspergillus 53,Penicillium 17 and Corollospora *** highest number of mangrove fungi have been recorded from the Pacific Ocean 553,which is the largest ocean,followed by Indian 408 and Atlantic Oceans *** distribution of mangrove fungi varied from ocean to ocean with only 109 taxa common to the Atlantic,Indian and Pacific *** the various countries reported for mangrove fungi,India accommodates the highest number(339)followed by Thailand 303,Malaysia 171,Florida Everglades,USA 134 and Brunei 134.A total of 60 different mangrove plants and their associates have been surveyed for mangrove *** results are discussed and compared with previous studies.
