Aim: To formulate a model capable of distinguishing astro-physical from primordial gravitational-wave signals. Methods: We used biased tracer formalism valid on large cosmological scales to introduce modeling basics and con-nected black holes as sources gravitational wave signal with dark matter. Results: LTC By deriving the using online tool Code for Anisotropies in Microwave Background (CAMB), we produced matter power spectrum it construct spectra lin-ear tracer. The were generated different Hubble constants bias parameter values, showing difference amplitude scale dependence spectra. Conclusion: Gravitational-wave background signals can be complementary probes data future space detectors like Laser Interferometer Space Antenna (LISA) others.
