1. A wireless communication apparatus comprising:
a radio frequency integrated circuit (RFIC) configured to generate a first digital sample data from an input signal;
a data compressor configured to compress the first digital sample data to a compressed data including first bit data of an exponent region and second bit data of a mantissa region based on a first data probability distribution having a plurality of probability ranges and a plurality data ranges, where each data range is associated with a corresponding one of the probability ranges and a number of bits for an exponent among a plurality of different numbers of bits;
a data decompressor configured to decompress the compressed data to a second digital sample data in a decompression manner corresponding to the compression manner of the data compressor;
a data transfer link configured to transfer the compressed data to the data decompressor; and
a processor configured to process the second digital sample data, the data compressor:
selecting a data range among the plurality of data ranges based on a value of the first digital sample data falling within boundaries of the selected data range;
setting the first bit data to have the number of bits for the exponent associated with the selected data range; and
setting the second bit data to have a number of bits based on the number of bits for the exponent and a total number of bits in the first digital sample data.
