One-bit Transceiver Cluster for Relay Transmission

Ultra-low-cost communication devices can enable massive deployment of disposable wireless relays. In this letter, we investigate the feasibility of using a 1-bit relay cluster to help a power-constrained transmitter. While the 1-bit transceiver enjoys the benefits of low cost and power consumption, it suffers from extreme information loss and failure of existing DSP techniques. To tackle these challenges, we propose a new receiver architecture design and nonlinear signal estimators. The results corroborate the effectiveness of our solution for the 1-bit relay transmission.
