Figure 4From: Performance limits of channel parameter estimation for joint communication and positioningComparison of approximate and exact normalized CRLBs vs. the sampling phase with γ p = 10 dB. The curves are labeled with “A” for approximate and “E” for exact. (a) Normalized CRLB of ε with K′ = 100. (b) Normalized difference of CRLBs with K′ = 100.Back to article page
