Add to ORKGThe distributed beamformer is a scheme which provides spatial diversity to combat the undesired effects of the wireless channel. The distributed beamformer requires strict carrier frequency and phase synchronization in order to maximize SNR at a destination for fixed transmit powers. This project investigated the synchronization of two such transmitters in a wired single path channel with off-the-shelf integrated circuits. Additionally, a stable hardware platform for an acoustic (wireless) implementation of such a distributed beamformer was provided
