Title:
CORRECTION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/129013
Kind Code:
A1
Abstract:
Embodiments of the present application provide a correction device and method. The correction device comprises: a first switching circuit, a second switching circuit, a third switching circuit, a fourth switching circuit, a modeling circuit and a correction circuit. Using the first switching circuit and the fourth switching circuit enables switching between M channel class signals and N beam stream class signals (N being less than M). Further, a modeling module and a correction module executing beam stream class modeling and correction on the beam stream class signal can substantially improve correction precision and simplify the correction device, reducing correction costs and the complexity and cost of a receiver.
