Title:
CHANNEL FLATNESS COMPENSATION METHOD AND APPARATUS, STORAGE MEDIUM, BASEBAND CHIP, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/072832
Kind Code:
A1
Abstract:
A channel flatness compensation method and apparatus, a storage medium, a baseband chip, and a device, applied in a transmitting link modulated by orthogonal frequency-division multiplexing. The method comprises: receiving an input vector of the current subcarrier after performed subcarrier mapping processing, and determining the current value of a preset configuration parameter corresponding to the current subcarrier (201); querying a preset frequency domain compensation table according to the current value of the preset configuration parameter, and determining a target compensation vector according to the query result (202); and determining an output vector of the current subcarrier according to the input vector and the target compensation vector, the output vector being used for participating in an inverse fast Fourier transform operation (203).
