One can get that with either one of sampling points increasing, the resolution rate
will increase.
Example 3 Keep the normalized separation constant, and simulate the resolution rate
w.r.t. the number of sampling points. Set d
0
t ¼ d
0
a ¼ d
0
d ¼ 0:1 and SNR D ¼ 0 dB, the
results are shown in Fig. 3.
One can see the results are similar to Fig. 2, where the resolution rate increases as
either sampling point number goes high.
