Figure 12From: A unified approach to sparse signal processingConvolutional encoders. (a) A real-field systematic convolutional encoder of rate 1 2 ; f [i]s are the taps of an FIR filter. (b) A non-systematic convolutional encoder of rate 1 2 , f1[i]s and f2[i]s are the taps of 2 FIR filters.Back to article page
