8192 Mbps wideband correlation for the KaVA

Daejeon hardware correlator is designed and implemented with performance of maximum 16 stations, 8192 Mbps, and 8192 channels output. However, VLBI observation is generally conducted with 1024 Mbps recording speed and the recording speed for wideband as like 2048 and 8192 Mbps are experimentally tested and increasingly conducted. In this paper, we introduce the required system so as to carry out the 8192 Mbps wideband correlation for maximum performance of Daejeon hardware correlator. Especially the data splitting and data transmission, data playback to correlator, and correlation processing method will be briefly introduced.
