Embodiment 1
[0055] Please refer to figure 2 , is a schematic flow chart of the FBMC-OQAM timing and channel estimation training sequence design method in an embodiment, the method comprising:
[0056] Step 1, obtaining a sequence of data symbols to be transmitted.
[0057] The transmitter of the FBMC-OQAM system groups the original data to be transmitted, and performs serial-to-parallel conversion on each group of original data to obtain the data symbol sequence to be transmitted. In one embodiment, each FBMC symbol includes an even number of working subcarriers, and each working subcarrier in the FBMC symbol is sorted in order of arrangement, and its sequence number is 0, 1, 2, ... M-1, and M is greater than even number of 0.
[0058] Step 2, generate training sequences.
[0059] The training sequence is used for timing synchronization and channel coefficient estimation in the frequency domain of the FBMC-OQAM system. Please refer to image 3 , is a schematic diagram of the trainin...
