In this paper, we propose two iterative synchronization schemes for distributed beamforming (DBF) with sidelobe control. The scenario that we address is that of a wireless sensor network surrounded by one intended base station (BS) and multiple unintended ones (serving otherWSNs). We consider two specific synchronization schemes with soft and hard constraints in terms of the received signal strength acceptable at the unintended base stations. The schemes merely require partial CSI at the BSs plus the broadcast of one-bit feedback messages from the intended BS messages to the sensor nodes.
