Abstract:
Provided are a pilot signal transmission method and apparatus, and a transmitting terminal. The method includes: setting a first pilot signal, a second pilot signal, and a third pilot signal on a same subcarrier; and transmitting the first pilot signal, the second pilot signal, and the third pilot signal respectively on three continuous symbols on the same subcarrier. The first pilot signal, the second pilot signal, and the third pilot signal are all nonzero data, a phase difference between the first pilot signal and the second pilot signal is 90 degrees, a phase difference between the third pilot signal and the second pilot signal is 90 degrees, and a phase difference between the first pilot signal and the third pilot signal is 180 degrees.

Claim (Index 18):
The pilot signal transmission apparatus according to  claim 17 , wherein\n the formula containing X(m 1 ) used for calculating the I(m 1 +1) is:\n I ( m 1+1)= X ( m 1) g m1 m1+1 , \n or \n I ( m 1+1)= X ( m 1) g m1 m1+1 +X ( m 1+2) g m1+2 m1+1 ; \n where \n g m1 m1+1 =\u222bg m1 ( t ) g m1+1 *( t ) dt , and \n g m1+2 m1+1 =\u222bg m1+2 ( t ) g m1+1 *( t ) dt,  \n wherein \u201c*\u201d is a conjugate operation, g m1  is a filter function for the second symbol of the three pilot symbols on the subcarrier m 1 ; g m1+1  is a filter function for the second symbol of the three pilot symbols on the subcarrier m 1 +1; g m1+2  is a filter function for the second symbol of the three pilot symbols on the subcarrier m 1 +2; the formula containing X(m 1 ) used for calculating the I(m 1 \u22121) is:\n I ( m 1\u22121)=\u2212 X ( m 1) g m1 m1\u22121 , \n or \n I ( m 1\u22121)=\u2212 X ( m 1) g m1 m1\u22121 \u2212X ( m 1+2) g m1+2 m1\u22121 , \n wherein \u201c*\u201d is a conjugate operation, g m1  is a prototype filter function for the second symbol of the three pilot symbols on the subcarrier m 1 ; g m1\u22121  is a prototype filter function for the second symbol of the three pilot symbols on the subcarrier m 1 \u22121; and g m1+2  is a prototype filter function for the second symbol of the three pilot symbols on the subcarrier m 1 +2.
