Figure 3From: Conditional downsampling for energy-efficient communications in wireless sensor networks Qualitative representation of the conditional pdf f ( x || x | < Δ t ). Due to the measurements that | x s (n)− w T x ~ t (n)|< Δ t are not introducing error since they are not estimated. The parameter Δ t should be chosen in order to guarantee that a fraction γ of the total measurements is transmitted.Back to article page
