Figure 11From: A novel method for sparse channel estimation using super-resolution dictionaryMSE performance using different resolution dictionaries.When λdelay=4, λDoppler=1, the performance of channel estimation is the best, while the accuracy performance on λdelay=λDoppler=2 is almost the same as that on λdelay=2, λDoppler=1; the over-sampling in the Doppler domain cannot improve the performance very much; the channel has a mild Doppler spread.Back to article page
