- W2998931352 abstract "The present generation of wireless communications systems, to a greater extent, do not optimally utilize the scarce radio spectrum and also not flexible in the allocation of the time-frequency resource. This may also be the case with the next generation systems if a viable solution is not found. Many researchers worked on resolving these two problems but suffered some limitations in their results, tools approaches and techniques used. The main problem was that they failed to collectively utilize the advantages of both the high spectral efficiency of Filter Bank Multicarrier Modulation Offset Quadrature Amplitude Modulation (FBMC-OQAM) and the efficient capacity property of large Multiple Input Multiple Output (MIMO) systems. In this paper, we shall propose to use the advantages of both systems in order to transmit FBMC-OQAM data symbols over a large MIMO system by employing a specific Space Time Transmission Scheme (STTS) of FBMC-OQAM for large MIMO. The transmission, however, will be prior to error correction using Hadamard scheme to double the spectral efficiency by restoring complex orthogonality in the imaginary field. The STTS will eliminate imaginary intrinsic interference, thereby enabling the efficient transmission of the FBMC-OQAM data over the large MIMO system. By employing the Hadamard scheme and STTS, we propose to develop a spectrally efficient large MIMO/FBMC-OQAM system with an improved capacity gain over a conventional MIMO/FBMC-OAQM." @default.
