I find that in some algorithm the received signal(atfer matched filter) is expressed as:
r(t)=∑Sk*exp{j*(Δωt+Θ)}*g(t-kT-τ)+n(t)
2 questions:
1, why is Sk a complex array? If so, it will impact the angle of correlation of r
2, why is there Δω after matched filter?
thanks a lot if anyone could help me!
