Detailed

The embodiments of the present disclosure are described in detail with reference to the accompanying drawings.

In some cases, one way to avoid interference of the pilot symbols of the FBMC system is to insert enough data 0 around the pilot symbols to isolate the pilot symbols and random data. Although this scheme guarantees the orthogonality of pilot symbols and data, it reduces the spectral efficiency and data transmission rate. Another solution to avoid interference of the pilot symbols of the FBMC system is to introduce a virtual symbol around the pilot symbols. By setting the value of the virtual symbols, the imaginary interference received by the pilot symbols is zero, but the scheme This will cause the auxiliary pilot energy to be too high.
