Multiple Gate Delay Tracking Structures for GNSS Signals and Their Evaluation with Simulink, SystemC, and VHDL

Figure 20

Example of VHDL hardware-based MEEs. MGD with uniform spacing (𝑎=[1,−0.7,−0.2]) is illustrated in blue-squared curve and MGD with decreasing spacing is illustrated (𝑎=[1,−0.9,0.2]) in red-circled. (𝑁_𝑔=3, pow_𝑛𝑐=1, Δ₁=0.25).
