Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] image 3 It is a schematic structural diagram of the data frame adopted by the single-carrier frequency domain equalization system of the present invention. As shown in the figure, the frame signal includes two identical training blocks (Pilot Block, PB), and the two identical training blocks are used for channel estimation , followed by consecutive Q FFT blocks. A complete FFT block is composed of a data block and a UW block. The block length N of the FFT block is the FFT size, and the length of the UW segment is M.
[0031] The unique word sequence is generally a chu sequence or a frank-zadaff sequence specified in the IEEE802.16a standard, and its length is generally an integer power of 2.
[0032] The single-carrier frequency domain equalization realization system of the present invention includes a channel estimation mod...
