Abstract: Provided are a data modulation method and apparatus, and a storage medium. The method includes: modulating a first data sequence to obtain a second data sequence; inserting a third data sequence into the second data sequence to obtain a fourth data sequence, where each of data, except for a first one and a last one in the fourth data sequence, of the third data sequence in the fourth data sequence satisfies that power of the each datum is equal to average power of two data adjacent to the each datum, and a phase of the each datum is within an angle between the two data adjacent to the each datum; and transmitting the fourth data sequence.

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.

Abstract: Disclosed is a method and system for performance test. The method includes: configuring a static channel between a transmitting end and a receiving end in a system configured with M transmitting antenna ports and N receiving antennas, wherein singular values of a N*M channel matrix of the static channel are equal, wherein, M=4 and N=4; or M=8 and N=4; or M=8 and N=8. The transmitting end transmits data to the receiving end by the static channel. When the M=4 and the N=4, the N*M channel matrix is a 4×4 channel matrix as follows: [ 1 j 1 j 1 - j 1 - j 1 j - 1 - j 1 - j - 1 j ] ; or a matrix obtained after any row swap or column swap operation is performed on [ 1 j 1 j 1 - j 1 - j 1 j - 1 - j 1 - j - 1 j ] .
