Message quantization in belief propagation: Structural results in the low-rate regime
Motivated by distributed inference applications in unreliable communication networks, we adapt the popular (sum-product) belief propagation (BP) algorithm under the constraint of discrete-valued messages. We show that, in contrast to conventional BP, the optimal message-generation rules are node-dep...
