1. A method, comprising:
obtaining, by a transmit end, P quadrature amplitude modulation (QAM) symbols;
performing, by the transmit end, inverse discrete wavelet transform (IDWT) or discrete wavelet transform (DWT) on the P QAM symbols, to obtain a first signal matrix with N rows and M columns, wherein P, N, and M are all positive integers;
transposing the first signal matrix, by the transmit end, to obtain a transposed first transpose matrix; and
outputting, by the transmit end, the transposed first transpose matrix.
