Figure 4From: A novel method for sparse channel estimation using super-resolution dictionaryComparison between dir N 0 π i − λ v q T s N 0 and dir N 0 i − v q T s N 0 . dir N 0 π i − λ v q T s N 0 has a quicker fade speed of side lobe and a smaller value of side lobe than dir N 0 i − v q T s N 0 . (a) v q T s N0=0.4, λ=2. (b) v q T s N0=0.5, λ=2.Back to article page
