Abstract
A method includes: A transmit end obtains P QAM symbols; the transmit end performs IDWT or DWT on the P QAM symbols, to obtain a first signal matrix with N rows and M columns, and transposes the first signal matrix, to obtain a transposed first transpose matrix, where P, N, and M are all positive integers; and the transmit end outputs the transposed first transpose matrix. Correspondingly, a receive end obtains a second signal matrix with M rows and N columns; the receive end transposes the second signal matrix, to obtain a transposed second transpose matrix; and performs DWT or IDWT on the second transpose matrix, to obtain P QAM symbols.

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.
An apparatus, comprising:
- a processor;
- and
- a memory storing a program that is executable by the processor, the program including instructions to:
- obtain P quadrature amplitude modulation (QAM) symbols;
- perform 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;
- transpose the first signal matrix, to obtain a transposed first transpose matrix;
- and
- output the transposed first transpose matrix.
