POWER ALLOCATION METHOD AND DEVICE

摘要

Provided in embodiments of the present invention are a power allocation method and device, the method comprising: determining a first power allocation value of each subcarrier in a single-carrier frequency domain equalization (SC-FDE) system and a second power allocation value of each subcarrier in an orthogonal frequency division multiplexing (OFDM) system according to a fading value of each of the subcarriers; determining a first weight value of the SC-FDE system and a second weight value of the OFDM system according to predetermined parameters; and determining a third power allocation value of each subcarrier in a hybrid carrier system according to the first power allocation value, the second power allocation value, the first weight value and the second weight value, and allocating power for input signals on each of the subcarriers in the hybrid carrier system according to the third power allocation value. The power allocation method and device provided in the embodiments of the present invention can improve communication performance of the system.
