Title:
A sending set, a receiving set, and a transceiver system
Document Type and Number:
Japanese Patent JP6109964
Kind Code:
B2
Abstract:
An object is to provide a transmitting device, a receiving device, and a transmitting and receiving system, which enable accurate decompression even if sparsity of an original input digital signal is low. Accordingly, a compressing unit 11 is included, which generates and outputs a compressed digital signal d that has been compressed, by converting an input digital signal x by use of a Walsh function and extracting a specific frequency component. The compressing unit 11 has an extracted observation matrix multiplying unit 12 that multiplies the input digital signal x by an observation matrix corresponding to a Walsh function of the specific frequency component, and generates and outputs, as the compressed digital signal d, the digital signal converted by the extracted observation matrix multiplying unit 12.
