“…These results are obtained with approximations that are detailed hereafter. In (30), L is first replaced byL, then |1 −L(e j2πf T )| 2 is approximated by a linear function of (f /f n ) 2r (asymptote) in the low frequency region (f f n ):…”

“…However, the joint multi-path KF in Equation (21) does not process each path independently, due to the presence of (F H p F p ) −1 in K eq(k) (see Equation (20)). This matrix depends on the power delay profile of the channel.…”

“…Reference [19] converts the vector of pilot subcarriers into L multi-path values where L is the number of multi-paths and applies a KF to each path. The VSSO approach (Vector State -Scalar Observation) is proposed in [20]- [23], where single-path KFs are used to separately track each tap of the discrete-time-equivalent (DTE) channel. This has the advantage of reducing the complexity of the joint estimation given by the VSVO (Vector State -Vector Observation) approach, reported in [24] and [25,Equations (18)- (21)].…”
