Problems solved by technology

However, since the DC bias voltage between each functional circuit in the wireless receiving system is not necessarily the same, the wireless receiving system will have a DC offset phenomenon
This DC offset phenomenon will not only destroy the data in the original received signal, but also make the signal dynamic range of the wireless receiving system smaller

Abstract

The invention relates to a signal receiving apparatus and a signal receiving method. The signal receiving apparatus is applied to a wireless system. The signal receiving apparatus comprises an adjusting circuit which is used for receiving a first receiving signal with a first DC signal and adjusting the first DC signal to generate the receiving signal with a second DC signal according to an adjusting signal, a first operation circuit which is used for generating an error signal according to the second DC signal and a target DC signal, and a second operation circuit which is used for computing an error signal change rate according to the error signal and updating the adjusting signal according to the error signal change rate.

Description

technical field [0001] The present invention relates to a signal receiving device and a signal receiving method, especially a signal receiving device capable of correcting DC offset and a related method thereof. Background technique [0002] In a wireless system, if the signal dynamic range covered by the wireless receiving system is larger, the signal receiving capability is stronger. However, since the DC bias voltages of each functional circuit in the wireless receiving system are not necessarily identical, a phenomenon of DC offset (DC offset) occurs in the wireless receiving system. The DC offset phenomenon will not only destroy the data in the original received signal, but also reduce the dynamic range of the signal of the wireless receiving system. Therefore, how to calibrate the DC offset phenomenon of a wireless receiving system in an efficient way has become an urgent problem to be solved in the industry. Contents of the invention [0003] Therefore, an object ...
