Pulse based Wideband Radio: Synchronization and Channel Monitoring

A reliable two-level synchronization method for pulse based wideband radio is presented. Coarse synchronization between transmitter and receiver is achieved by monitoring the channel at baseband speed, using a quadrature receiver setup to track and compensate for clock frequency offset. Precision alignment of the receiver on the transmitted pulse stream is based on the Vernier principle. Advantages of this approach include that it relies on the accuracy of a limited number of circuits, rather than on the processing speed of the entire receiver.
