example 1
[0035] This particular embodiment is a FBMC system with 256 subcarriers, selects the modulation of QPSK, and each carrier sends 20 symbols, and the filter used is a Phydas filter with a length of 1024, for 4 around the pilot symbol Auxiliary pilot symbols are designed, and the position of S is as attached figure 1 As shown, and S needs to cancel the imaginary part interference of the data in the surrounding 3×9 area on the pilot symbols.
[0036] (1) Obtain the interference coefficient A=[a of the auxiliary pilot symbols around the pilot symbols to the pilot symbols 1 ,a 2 ,a 3 ,a 4 ]=[0.2393,-0.5644,0.5644,-0.2393], the data D around the pilot symbol=[d1 , d 2 , d 3 ,... d 22 ] T (1 pilot symbol and 4 auxiliary pilot symbols are removed in the 3 × 9 area, and there are 22 data in total), the data around the pilot symbol interfere with the pilot symbol B=[b 1 ,b 2 ,...,b 22 ]=[0.0054,0.0429,0.1250,0.2058,0.2058,0.1250,0.0429,0,-0.0668,0,0,0.0668,0,-0.0054,0.0429,-0.1...
example 2
[0055] This particular embodiment is a FBMC system with 256 subcarriers, selects the modulation of QPSK, and each carrier sends 20 symbols, and the filter used is a Phydas filter, which performs 8 auxiliary pilot symbols around the pilot symbol design, the position of S is as attached figure 2 As shown, and S needs to cancel the imaginary part interference of the data in the surrounding 3×9 area on the pilot symbols.
[0056] (1) Obtain the interference coefficient A=[a of the auxiliary pilot symbols around the pilot symbols to the pilot symbols 1 ,...,a 8 ]=[0.2058,0.2393,0.2058,-0.5644,0.5644,0.2058,-0.2393,0.2058], the data D around the pilot symbol=[d 1 , d 2 , d 3 ,... d 18 ] T (1 pilot symbol and 8 auxiliary pilot symbols are removed in the 3 × 9 area, there are 18 data in total), the data around the pilot symbol interfere with the pilot symbol B=[b 1 ,b 2 ,...,b 18 ]=[0.0054,0.0429,0.1250,0.1250,0.0429,0.0054,0,-0.0668,0,0,0.0668,0,-0.0054,0.0429,-0.1250,-0.12...
