Embodiment Construction
[0058] The phase noise correction method at the receiving end of the multi-antenna orthogonal frequency division multiplexing system proposed by the present invention has a flowchart as figure 1 As shown, including the following steps:
[0059] (1) At the transmitting end of the multi-antenna orthogonal frequency division multiplexing system, in the process of sending data, a pilot orthogonal frequency division multiplexing symbol is placed in the data orthogonal frequency division multiplexing symbol at a set interval, and the data is positive. The sub-carriers with non-zero data in the cross-frequency division multiplexing symbols and pilot orthogonal frequency division multiplexing symbols are valid sub-carriers;
[0060] (2) For the mth antenna of the transmitting end, select n effective subcarriers among the N effective subcarriers of each pilot orthogonal frequency division multiplexing symbol to place the pilot, and place the effective subcarrier mark after the pilot. Is p 1...
