Abstract

The related OM multi-carrier transmission and receiving device based on MBFB comprises: using MBFB to separate broadband channel into some orthogonal or quasi-orthogonal sub-channels, then overcoming the high sensitivity on frequency / time bias of traditional technique, and using OM transmission in every sub-channel to inhibit noise and improve communication performance.

Description

Technical field [0001] The present invention relates to multi-carrier transmission technology, and more specifically, to an orthogonal multiplexed multi-carrier transmission and reception device based on a multi-band filter bank, and a receiving device and method thereof. Background technique [0002] In recent years, wireless communication systems have developed rapidly toward broadband; along with this development trend, the bandwidth occupied by a single channel of the wireless communication system is getting higher and higher, the complexity of wireless receivers has also continued to grow, and the implementation complexity has become higher and higher. At the same time, according to research findings in recent years, in order to effectively improve the throughput of the system, the combined multiple access technology of frequency division multiple access technology (FDMA) and time division multiple access technology (TDMA) will become the main multiple access technology of f...
