摘要： A method and a device for reducing a signal peak value are adapted to solve a problem that overall performance of a system is significantly degraded caused by allocating a same weight to each sub-carrier so as to averagely distribute a peak clipping noise to each sub-carrier. The method includes: receiving a signal (21); and performing a peak clipping processing on the received signal by using a peak clipping signal (25). The peak clipping signal is formed according to a peak clipping weight factor and the received signal, or according to a frequency domain error vector magnitude (EVM) and the received signal. In the method, a weight of each sub-carrier is set according to the peak clipping weight factor (the peak clipping weight factor includes, but is not limited to, an encoding mode, a constellation mapping mode, a transmit power, and a receiving quality class) or the frequency domain EVM during the peak clipping processing, that is, a large weight is allocated to the sub-carrier having good anti-interference capability, and a small weight is allocated to the sub-carrier having poor anti-interference capability, thereby improving the overall performance of the system.

摘要： Embodiments of the present invention provide a method and an apparatus for generating a standard cancellation signal, and belong to the communication technology field. An embodiment includes: setting weight values according to frequency points of a current cell and its neighboring cells; according to the frequency points of the current cell and neighboring cells and the weight values of the frequency points, performing Fourier transform to obtain a corresponding time-domain signal; and performing highest amplitude normalization on the time-domain signal and performing a cyclic shift to obtain a standard cancellation signal. The embodiments generate a standard cancellation signal according to frequency points of the current cell and its neighboring cells, so that the current cell and its neighboring cells share the peak clipping noise, and therefore helping improve the peak clipping performance of the current cell or reduce the EVM distortion. In addition, due to the existence of large-scale fading, actual interference of the peak clipping noise in the current cell on the neighboring cells is small.
