Findings
Effective demodulation across all sky locations
Enables detection without matched filtering
Compatible with excess power triggers and fast chirp transform
Abstract
A simple method is presented for removing the amplitude, frequency and phase modulations from the Laser Interferometer Space Antenna (LISA) data stream for sources at any sky location. When combined with an excess power trigger or the fast chirp transform, the total demodulation procedure allows the majority of LISA sources to be identified without recourse to matched filtering.
