<p><P>PROBLEM TO BE SOLVED: To improve efficiency in processing an input signal so as to reduce load. <P>SOLUTION: A receiving device comprises: detection means; decode means; and correlation determination means. The detection means detects presence/absence of a specific pulse pattern which identifies a preamble of mode S response from an input signal. The decode means decodes the mode S response configured by the preamble and data block when the detection means detects the preamble of mode S response. The correlation determination means determines correlation between a level of a phase value of each pulse included in data block following the preamble and a level of a phase value of the preamble when the detection means detects the preamble of mode S response. When the correlation result meets prescribed conditions, the correlation determination means outputs decode stop notification for stopping decoding data block following the preamble to decode means. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
