Abstract
The present invention relates to a receiving apparatus 20 that receives burst signals, each including a synchronization section and a data section following the synchronization section, from a plurality of sources in a time division manner. The receiving apparatus 20 includes amplifying units 102 and 113 that amplify each burst signal; a detecting unit 116 that detects arrival of the burst signal from an output signal from the amplifying units 102 and 113; a comparing unit 104 that compares the output signal from the amplifying units 102 and 113 with a predetermined threshold value and outputs a binary signal; and a control unit 108 that sets the timings of changing a receive function during the synchronization section by adding delay times Dai and Dbi to a detection time point where the detecting unit 116 performs an output. The control unit 108 is configured to be able to change the delay times Dai and Dbi in a plurality of ways.
