Abstract:
Provided is a data processing method and apparatus. The method includes: performing an inverse fast Fourier transform (IFFT) on data and processing the data with a preset function. The preset function is the product of a first function and a second function. The first function is a function in a time domain obtained by performing a Fourier transform on a root-raised cosine function in a frequency domain. The second function is in the time domain.

Claim (Index 10):
The method according to  claim 1 , wherein the preset function comprises: W(t)=IFsry(t)*x(t), IFsry(t) represents the first function, and x(t) represents the second function;\n wherein IFsry(t)=IFFT(sry(\u0192)), sry(\u0192)=\u221a{square root over (y(\u0192))}, y \ue8a0 ( f ) = { A 0 \u2264 \uf603 f \uf604 < f 0 \ue8a0 ( 1 - \u03b1 ) A 2 \ue89e ( 1 + cos \ue8a0 ( \uf603 f \uf604 - f 0 \ue8a0 ( 1 - \u03b1 ) 2 \ue89e \ue89e f 0 \ue89e \u03b1 \ue89e \u03c0 ) ) f 0 \ue8a0 ( 1 - \u03b1 ) \u2264 \uf603 f \uf604 < f 0 \ue8a0 ( 1 + \u03b1 ) 0 \uf603 f \uf604 \u2265 f 0 \ue8a0 ( 1 + \u03b1 ) ; wherein \u0192 represents a frequency, IFFT(.) represents IFFT on a function from a frequency domain into a time domain; the |.| is an absolute-value operator; A is a preset value, \u03b1 is a roll-off factor and has a value range of [0, 1]; \u0192 0 =\u0192 1 /2, wherein \u0192 1  represents a spectrum width of the first function, and f 1 = 1 T , wherein T represents a symbol interval of the multicarrier system; x \ue8a0 ( t ) = { B 0 \u2264 \uf603 t \uf604 < T 0 \ue8a0 ( 1 - \u03b2 ) B 2 \ue89e ( 1 + cos \ue8a0 ( \uf603 t \uf604 - T 0 \ue8a0 ( 1 - \u03b2 ) 2 \ue89e \ue89e T 0 \ue89e \u03b2 \ue89e \u03c0 ) ) T 0 \ue8a0 ( 1 - \u03b2 ) \u2264 \uf603 t \uf604 < T 0 \ue8a0 ( 1 + \u03b2 ) 0 \uf603 t \uf604 \u2265 T 0 \ue8a0 ( 1 + \u03b2 ) ; wherein t represents time, B is a preset value, \u03b2 is a roll-off factor and has a value range of [0, 1]; T 0 =T 1 /2, wherein T 1  is a parameter representing a width of the second function in the time domain, T 1 (1+\u03b2)=N\u00d7T, wherein N is a real number greater than or equal to 1.
