Scientific paper

Pulsar coherent de-dispersion experiment was carried out by using the 25m Nanshan radio telescope in the Urumqi Observatory. It uses a dual polarization receiver operating at 18cm and a VLBI back-end, Mark5A. The data processing system is based on a C program on the Linux and a 4-node Beowulf cluster. A high quality data acquisition system and a cluster with more processors are needed to build an online pulsar coherent de-dispersion system in the future.
