Danny Price colloquium: HIPSR: A reconfigurable digital signal processing systems for the Parkes multibeam rec

Marsfield

Abstract

HIPSR (HI-Pulsar) is a new digital backend for the Parkes 21cm multi-beam receiver, which will provides larger instantaneous bandwidth than the existing backend, as well as increased processing power for pulsar observations. Moreover, this new backend is able to provide finer spectral resolution, and increased dynamic range through 8-bit sampling.

The development of the new backend was driven by three main science goals: to provide large bandwidth, high resolution spectra suitable for HI stacking experiments; to investigate novel RFI mitigation algorithms and spatial filtering techniques; and, to upgrade the Berkeley Parkes Swinburne Recorder (BPSR), used in the High Time Resolution Survey.
