Abstract

Abstract We present a preliminary application of the Coherent Oscillation Detection and Encoding System (CODES), a novel method for detecting gravitational waves using prime-based encoding and phase-locking, to the GW190521 event detected by LIGO. CODES encodes strain data into a complex function C(x,t)=∑p=2,3,5,71pei(2πlog⁡(p)t+χpx) C(x,t) = \sum_{p=2,3,5,7} \frac{1}{p} e^{i(2\pi \log(p) t + \chi_p x)} C(x,t)=∑p=2,3,5,7​p1​ei(2πlog(p)t+χp​x), enhancing coherence through phase alignment to compute a Coherence Score (CCS). Using H1 detector data from GPS 1242442965.779297 to 1242442968.220459, CODES identified a peak CCS of 1.945987e-38 at GPS 1242442967.256348, closely aligning with the known merger time of 1242442967. This suggests CODES’s potential as an alternative detection technique. However, this is a single-event analysis with unoptimized parameters. Ongoing work includes testing CODES on additional events (e.g., GW150914, GW170817), optimizing phase shifts, and conducting statistical significance tests to prepare for a journal submission. This preprint timestamps the method’s initial success.
