Abstract: A communication system includes a plurality of nodes connected in a daisy-chain via respective bus links, wherein the plurality of nodes are configured for full duplex, synchronized communication via a carrier-based modulation scheme over the bus links. A node is configured to: transmit a downstream synchronization control header (DnSCH) to a downstream node; receive an upstream synchronization response header (UpSRH) from the downstream node; measure a delay between the DnSCH and the UpSRH; send delay information to the downstream node in a DnSCH; receive a time adjusted UpSRH; and communicate with the downstream node and any upstream node over frames based on the delay information. The frames may include a header; a flexible payload defined by a stream mapping that assigns a byte location within the flexible payload to a stream; and a footer.
