“…The proposed TRX is the first BCC TRX utilizing DFE, and achieved 150 Mb/s, which is the fastest data rate reported to-date. Compared with the previous record (100 Mb/s) [29], which employed galvanic coupling, the proposed TRX improved the maximum data rate by 1.5 times with the 20-fold increase in the test channel distance. Slightly lower data rates of 80 Mb/s and 60 Mb/s with capacitive coupling have been demonstrated in [24] and [26], respectively.…”

“…Previously reported BCC transceivers adopted either RF modulation [16], [20]- [24], [28] or digital baseband signalling [17]- [19], [25], [26], [29] without significant compensation for channel distortion, by assuming relatively flat frequency band. RF-based TRXs modulate data onto the flat frequency bands.…”

“…For example, a typical analogue equaliser [14] cannot compensate for all the irregularly shaped ISIs (Figure 7d) due to its limited degrees of tuning freedom. Moreover, while the galvanic-coupling implementation gives resilience to environmental changes, due to increased attenuation TRX in [29] reports successful communication only at a 1 cm channel.…”

“…Body-channel communication (BCC) -synonymously known as human-body communication (HBC), which uses the human body as a signal-transmission medium, is now a widely-accepted physical layer (PHY) owing to its superiority in terms of power consumption and data rate [16]. Following the first successful BCC implementation using an IC chip [17], researchers have developed many more BCC transceivers with advanced schemes [16]- [29]. In general, two approaches have been investigated in designing BCC transceivers: RF communication and digital baseband communication.…”

This paper presents the body channel communication technique that first adopts decision feedback equalisation. For the first time, we characterised post-cursor intersymbol interference of a single-bit pulse response of a human body channel for decision feedback equalisation achieving the first body channel communication faster than 100 Mb/s. In the proposed technique, an 8-tap decision feedback equaliser is utilised at the receiver to compensate for intersymbol interference of the body channel. The experimental results show that the proposed prototype transceiver achieved the highest data rates of 150 Mb/s and 10 Mb/s along 20-cm and about 100-cm body channels, respectively. Compared to the previous best result measured for the same body-channel distance of about 100 cm, the data rate is improved by ten times, showing that the proposed technique can significantly increase the speed of body channel communication.

“…The work is analyzed in the software environment and not compactable to real-time HBC. Jeon et al [22] discuss the BCC TR for Bionic arms using a galvanic coupling. The BCC TR is designed using CMOS 0.18 µm, which provides better energy efficiencies of 4.75 pJ/b and 26.8pJ/b for TX and RX, respectively, and improves the 10-8 BER using a galvanic coupling at 100Mbps data rate.…”

Body coupled communication (BCC) is an efficient networking approach to body area network (BAN) based on Human-centric communication. The BCC provides interference only between humans in very close proximity. In this work, an efficient Physical layer (PHY) based digital transceiver) is designed for BCC. The digital transceiver Module mainly contains a Digital transmitter (TX) with Manchester encoder, clock synchronization unit, and Digital receiver (RX) with Manchester decoder. The TX and RX modules are designed using a finite state machine as per the IEEE 802.3 Standards. The complete work is also varied for BAN applications by connecting two Application layer transceivers and two Physical layer-based digital transceivers. The architecture is simulated in a Model-sim simulator. The complete Module is synthesized using different FPGA families, and the hardware design constraints are contrasted. The digital transceiver works at 231.28 MHz operating frequency, consumes 0.113W power, and provides a 7.7 Mbps data rate and 4.67 Kbps/Slice efficiency on Artix-7 FPGA. The proposed transceiver is also compared with existing digital transceivers with hardware constraints improvements.
