SDQNR of quantized gossip schemes. The realized SDQNR vs number of quantization bits (q-bits for q=2,…,10) using a Frasca’s symmetric quantized gossip scheme and b Kashyap’s quantized gossip scheme. This simulation uses M=2, K=5, N=90; the network is a RGG, \(\mathcal {G}(N,0.6)\). The solid line in both plots shows the signal-to-noise ratio of the quantized version of ground truth Prony’s sequence, i.e. \(\{Q_{q}(\mathcal {R}(k))\}_{k}\) for each q
