Abstract: A wireless communication apparatus includes a radio frequency integrated circuit (RFIC) configured to receive an input signal to generate a digital sample signal from the input signal, a data compressor configured to compress the digital sample signal according to a compression manner based on a data probability distribution of the input signal varying based on a receivable signal amplitude range of the RFIC, a data decompressor configured to decompress the compressed digital sample signal on the basis of a decompression manner corresponding to the compression manner to generate a decompressed digital sample signal, a data transfer link configured to transfer the compressed digital sample signal to the data decompressor, and a processor configured to process the decompressed digital sample signal.

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.
