  A low-complexity all-analog circuit is proposed to perform efficiently Analog
Joint Source Channel Coding (AJSCC), which can compress two or more sensor
signals into one with controlled distortion while also being robust against
wireless channel impairments. The idea is to realize the rectangular-type AJSCC
using Voltage Controlled Voltage Sources (VCVS). The proposal is verified by
Spice simulations as well as breadboard and Printed Circuit Board (PCB)
implementations. Results indicate that the design is feasible for
low-complexity systems like persistent wireless sensor networks requiring low
circuit power.
