“…Figure 9 shows the functional top-level block diagram of the implemented P2P radio node that is based on prior work in [ 16 ]. Each node comprises a custom RF (radio frequency) board with an AD9364 transceiver (the radio), a crystal oscillator and miscellaneous support circuitry, the ASIC accelerator chip, and a ZedBoard.…”

“…The signal processing core is able to detect the syncword regardless of the phase and frequency mismatch between the TX and the RX local oscillators (LOs). Prior works describe in detail the operations performed by the signal processing core [ 14 , 16 ]. If the syncword is detected, the state of the PCO is advanced.…”

“…To incorporate duty-cycling, the radio circuitry should interface with a duty-cycle controller that can keep track of the synchronization state and safely turn off-and-on various components according to a schedule. The operation of the controller is described in more detail in prior work [ 16 ]. Figure 11 shows the state transition timing for the AD9364 radio when receiving and transmitting the syncword.…”

“…The node’s radio is first used in RX mode to listen for possible transmission from faster nodes, and then in transmit mode when the node reaches reset. Sections III D and E in [ 16 ] provide more detail.…”

“…A key design feature that determines the network’s ability to duty-cycle and scale is a symmetric synchronization protocol that does not rely on dedicated beacons or relays. Previous work has demonstrated low-power baseband timing circuitry that enables scalable synchronization for narrowband communication and rudimentary mesh networking with commercial radios [ 14 , 16 ]. This paper expands on the previous work with a system-level analysis of the PCO-based synchronization parameters, which is then validated by measured results.…”

Bluetooth Low Energy (BLE) mesh networks enable diverse communication for the Internet of Things (IoT). However, existing BLE mesh implementations cannot simultaneously achieve low-power operation, symmetrical communication, and scalability. A major limitation of mesh networks is the inability of the BLE stack to handle network-scalable time synchronization. Pulse-coupled oscillators (PCOs) have been studied extensively and are able to achieve fast and reliable synchronization across a range of applications and network topologies. This paper presents a lightweight physical (PHY) layer accelerator to the BLE stack that enables scalable synchronization command with a PCO. The accelerator is a fully digital solution that can be synthesized with only the standard cells available in any silicon technology. This paper provides a detailed analysis of PCO-based BLE mesh networks and explores per-node system-level requirements. Finally, the analytical results are validated with measurements of a custom radio node based on the ubiquitous AD9364 transceiver.

With the quickly development of the Internet of Things technology, Bluetooth (BLE) protocol has been increasingly adopted in consumer communication applications, industry communication utilization, and even positioning requirement, due to its advantages such as low power consumption, low cost, and low complexity. Especially the outstanding low power capability compared with other short-range communication protocol, many power limited AIoT (Artificial Intelligence IoT) devices select BLE as basic component. So, the low power, high performance, and small area BLE module become the key point of successful of whole AIoT system. In BLE system, the baseband data processing is the foundation. A good hardware circuit design of BLE baseband can improve BLE module performance and decrease power simultaneously. This paper analyzes the baseband data processing function of BLE in detail, and designs the baseband transmission data processing RTL circuit IP using Verilog HDL Hardware description language based on BLE protocol. The IP includes CRC verification module, whitening module and coding mapping function module. The RTL design is simulated and evaluated in workstation server with Synopsys VCS tool. The simulation results show that this design can achieve the Low-power BLE Bluetooth baseband function.
