Figure 6From: Preamble-based frequency-domain joint CFO and STO estimation for OQAM-based filter bank multicarrierRMSE of the STO δ , with δ∈ [ −32,32] on both an AWGN channel and a multipath channel. On the AWGN channel, the STO was estimated with both the reference function z(δ,ϕ) and its linear approximation. On the multipath channel, the STO was estimated with the reference functions z(δ,ϕ) and zmult(δ,ϕ) and their respective linear approximations.Back to article page
