New Description: The new technical field of this invention This creation is related to wireless communication systems. More specifically, the present invention relates to a hybrid orthogonal frequency division multiple access system and method. The prior art unfinished wireless communication system is expected to provide a wide-band service such as access to the user's wireless Internet. This wide-band service requires transmission over a wireless channel and high-light capability, which is typically time-dispersive and frequency selective. The wireless channel is limited by internal symbol interference (ISI) caused by limited spectrum and multipath fading. For the next generation of wireless communication networks, Forward Division Multiplexing (OFDM) and Orthogonal Frequency Division Multiple Access (〇FDMA) are the most promising solutions. / Orthogonal Frequency Division Multiple Tool has high spectral efficiency because the subcarriers used in the Orthogonal Frequency Division Multiplexing System overlap in frequency and can be used throughout the subcarriers. Suitable modulation coding scheme (MCS) ). In addition, the orthogonal division is much simpler because the baseband modulation and demodulation can be performed by simple inversion fast Fourier transform (IFFT) and fast Fourier transform (FFT) operations. Other advantages of the orthogonal frequency division multiplexing include a simple receiver structure and excellent robustness in a multipath environment. The positive two-segment frequency and the orthogonal frequency division of the township re-access have been adopted by Xuxiang Wireless/Yes, 'Youtong' and the land system are not allowed to be used, such as digital sound broadcasting (DAB), walking type digital ear day Broadcast (DAB-T), ieee, and now (10)n non-synchronous digital subscriber line (ADSL), and is considered in the third generation partner M298282
