SKA Project Series
SKA-PSS - SKA CSP Pulsar Search LMC Detailed Design Document

C.Baffa, E.Giani

INAF Osservatorio Astrofisico di Arcetri

Abstract

The purpose of this document is to describe the Detailed Design for the SKA Phase 1 CSP Pulsar Search Sub-element LMC (PSS.LMC), with a solution that applies to both SKA Phase 1 Mid (CSP_Mid) and SKA Phase 1 Low (CSP_Low). In this document we present the Arcetri contribution to the SKA CSP Pulsar Search Detailed Design Document along with some general presentation (Author A.Kastergiou and the SKA TDT Team).

The Pdf version of this report will be publicy available after Spring 2018 CDR

SKA Project Series
SKA-LOW transient buffer proposal

G. Comoretto

INAF Osservatorio Astrofisico di Arcetri

Abstract

The SKA-LOW telescope must include a transient buffer.

The buffer must be able to capture up to 600 seconds of station data, from all the 512 LFAA stations, for a 150 MHz total bandwidth. Different proposals for the buffer implementation are compared.

SKA Project Series
LFAA tile beamformer functional model

S. Chiarucci, G. Comoretto

INAF Osservatorio Astrofisico di Arcetri

Abstract

A complex digital signal processing system like the LFAA tile beamformer requires extensive simulations to test its compliance with the system specifications.

A Matlab simulator, composed of a general purpose signal generator, a simulation pipeline for the actual processing, and a set of analysis tools to extract the significant parameters from the processed data has been designed and tested.

The simulator has been used to test various parameters, as added digital noise, calibration capabilities, spectral response, channel to channel insulation and beamforming losses.

SKA Project Series
LFAA tile beamformer signal processing

G. Comoretto, C.Belli

INAF Osservatorio Astrofisico di Arcetri

Abstract

The LFAA digital signal processing chain is described. The processing starts with the ADC sampling, and includes channelization, calibration, beamforming and all rescaling and requantization stages present in the processing chain. Expected signal level and numeric coefficients embedded in the processing are detailed. The description is purely functional, i.e. it does not include implementation details that do not affect the signal. Time tagging and auxiliary data (total power, diagnostic spectra) produced by the processing chain are also described.
