Abstract: A digital signal processing circuit includes an analog gain compensator that compensates for an analog gain of a baseband signal including a plurality of component carriers (CCs) to output a compensated baseband signal; an analog-to-digital converter (ADC) that converts the compensated baseband signal into a first digital signal; a plurality of filtering circuits that generate a second digital signal from the first digital signal; and a control circuit. Each filtering circuit sequentially filters the first digital signal so that a corresponding one of the second digital signals retains one CC among the CCs, compensates for a digital gain, and a performs down-sampling. The control circuit generates an analog gain control signal for controlling the analog gain based on the second digital signals and a digital gain control signal for controlling the digital gain.

Abstract: An operating method of a terminal performing a cell search using first and second memories for buffering input samples includes detecting a first primary synchronization signal (PSS) group from a first input sample group while buffering the first input sample group in the first memory in a first interval. While buffering a second input sample group in the second memory in a second interval following the first interval, the method detects a second PSS group from the second input sample group, and a first secondary synchronization signal (SSS) group corresponding to the first PSS group from the first input sample group. While buffering a third input sample group in the first memory in a third interval following the second interval, the method detects a third PSS group from the third input sample group, and a second SSS group corresponding to the second PSS group from the second input sample group.
