Design method for pilot frequency in next generation broadcast wireless (NGB-W) communication system

The invention provides a design method for the pilot frequency in a next generation broadcast wireless (NGB-W) communication system. The design method at least includes the following steps that a pilot frequency unit value of an OFDM symbol in each NGB-W frame is generated by a pilot frequency reference sequence in a modulation mode, wherein m is a frame index, l is an OFDM symbol index, and k is an effective subcarrier index; the reference sequence is generated by a symbol level pilot frequency PRBS and a frame level PRBS together. According to the design method for the pilot frequency in the NGB-W communication system, various types of wireless channel scenes are considered, wherein the signaling pilot frequency and the frame tail pilot frequency are high enough in density and can be used for channel estimation of severe channel environments under the limit borne by the system; the timed slender synchronization performance and decimal carrier slender synchronization performance of a continuous pilot frequency system are basically equivalent in the NGB-W system and a DVB-T2.
