【 摘 要 】

Beyond 4G, communication systems will be highly flexible and more congested. This is because of the increased demand for wireless applications, such as machine type communications (MTC) aside from the cellular mobile communications. Hence the need for the next generation, 5G, becomes essential. In the 4G systems, the cyclic-prefix orthogonal frequency division multiplexing (CP-OFDM) has been adopted as a modulation technique. However, CP-OFDM suffers from the spectrum waste problem, because of the high out of band (OOB) emission. Thus, not all frequency spectrums will be useful. On the other hand, the required, increased demand, for high data rate motivated the industry to find another candidate as a modulation technique to be adopted in the next generation. Different candidates have been introduced; the Filter Bank Multi-Carrier (FBMC) is one of the promising candidates for that job. In this paper, we will show that the FBMC can be employed in 5G communication systems and can exploit almost, all, the advantages of the previous, CP-OFDM, system with little increment in the complexity, such as the implementation of multiple input-multiple output (MIMO) antenna diversity, and the high throughput with noteworthy mobility speeds.
