Abstract :
For multi-node networks, a distributed compressed sensing scheme based on one-bit quantization is proposed, where signals at each node consist of common component and innovation component. To reduce the transmission cost, each node derives the measurements as the sign information of the compressed samples by using one-bit quantization. Based on the received sign information from different nodes, two joint recovery algorithms are designed to recover the signal of each node. Simulation results show that the proposed scheme outperforms both the independent reconstruction scheme and the scheme based on multi-bit quantization.
