A semiconductor device includes a first ADC configured to sample an input signal based on a first clock signal, quantize the input signal with a first gain, and output a plurality of first output signals, and a second ADC configured to sample the input signal based on a second clock signal obtained by delaying the first clock signal, quantize the input signal with a second gain, and output a plurality of second output signals. The device includes a gain mismatch estimator configured to calculate first and second values which are averages of absolute values of the first output signals and the second output signals, and calculate first and second gain correction values using the first and second values. A gain mismatch compensator is configured to output a plurality of corrected first output signals and corrected second output signals, according to the first and second gain correction values.

Semiconductor device

Provided are a method and an apparatus of transceiving a signal using a link adaptation in a communication system, particularly, a method of dividing a resource region into a plurality of resource regions, and applying different line adaptations to the resource regions. A method of controlling a link of a terminal in a mobile communication system receives at least two downlink channel signals to estimate states of received channels, generates a channel discrepancy report when states of channels exceed a preset threshold, and reports the channel discrepancy report to a base station through a preset uplink channel. A method of controlling a link of a base station receives a channel discrepancy report through an uplink channel, and determines MCS and transmission power of downlink channels based on the received channel discrepancy report and transmits the determined MCS and transmission power to the terminal through a downlink channel.

Method and device for applying adaptive link in communication system

A link quality reporting method and apparatus, and a carrier selection method and apparatus, for a multicarrier communication system utilizing carrier aggregation are disclosed. In the system, the user equipment measures, for each component carrier divided into a Physical Downlink Shared Channel (PDSCH) resource region and a Physical Downlink Control Channel (PDCCH) resource region, link quality of the PDSCH resource region and the PDCCH resource region of the component carrier and sends measured link quality information as feedback information to the base station, and the base station adaptively selects a set of component carriers for control information transmission (i.e., a PDCCH Component Carrier (CC) SET) and a set of component carriers for data transmission (i.e., a DownLink (DL) CC SET) on the basis of the feedback information.
