Figure 1From: Conditional downsampling for energy-efficient communications in wireless sensor networks Block diagram of a generic encoder-decoder transmission scheme. The source is generating the desired signal x(n) at a rate R (samples/s). The signal y(n) is the encoded version of x(n), and it is transmitted at a rate γ R, where γ≤1. The signal x ~ (n) is the reconstruction of the desired signal x(n) after the decoder.Back to article page
