In this paper, a narrow band wireless body area network (WBAN) model based on IEEE 802.15.4 standard is employed for transmitting vital biomedical signals such as electrocardiography (ECG) or Fetal ECG. To restrict the sampling rate and energy consumption to minimum, compressed sensing based on exploring the sparsity of structured blocks in the signal is employed. The center frequency of the ZigBee transceiver is 2.4 GHz. At the transmitter, the signal is quantized, coded and modulated using offset quadrature phase shift keying (OQPSK). At the receiver, which is a mirror image of the transmitter, the normalized least mean square (NLMS) adaptive equalizer is added. To improve the quality of the reconstructed signal, the double-density dual tree discrete wavelet transform (DWT) is employed for denoising, and is compared with other denoising methods. The bit error rate is calculated over a range of signal-to-noise ratio values, and the system feasibility is evaluated using efficient metrics. Results indicate that the proposed system can transmit signals with minimum energy consumption, meanwhile reconstructing them with high quality at the receiver.

The emerging non-volatile memory technologies open novel perspectives for original highly-efficient and flexible architecture design. Dense integration of non-volatile memristors close to logic gates and circuit wires allows for new dimensions of reconfiguration and low power design. In this paper we present a review of the recent contributions that have investigated the use of memristors for different applications in digital design. Based on this review, and considering the widely used fast Fourier transform (FFT), we investigate for the first time a novel memristor-based reconfigurable FFT architecture. The proposed original architecture allows an efficient support of any combination of radix-2 and radix-3 butterflies. Scalability is ensured through a 2D mesh based topology and fast reconfiguration can be achieved using memristor-based interconnections.

The monitoring healthcare systems that can be used by patients wherever they are, has become very important for today efficient healthcare. Wireless body area network is one possible realization of these systems. Based on IEEE 802.15.6-2012 standard, this paper proposes a low power architecture of Human Body Communication transceiver for Wireless Body Area Network. A new efficient frame synchronization algorithm based on adaptive threshold is adopted. The proposed design is coded and simulated using MATLAB software. Then, the transceiver is implemented using Verilog and synthesized to 90nm CMOS technology. The implemented architecture meets all the standard requirements, consumes 0.63mW, and operates at a clock frequency of 42MHz.

This paper presents a novel implementation of the memorization system of the Non-Binary LDPC Decoder. The proposed approach relies on new implementations of STT-MRAM with power gating capabilities. A new data mapping has been defined to fit in with the physical dimensions of these implementations. The decoder adopting the devised memorization system has been compared to SRAM-based one which is used in almost all traditional decoders in order to demonstrate the feasibility of using power-gated MRAM. The obtained results show a significant reduction in the consumed energy by the memory reaching up to 78.45%.

Two kinds of RF power combiner are studied. Matched Wilkinson combiner shows very good linearity but low power efficiency. Unmatched Wilkinson combiner used at the output of class-B amplifiers can be optimized in order to obtain the same good linearity of a matched Wilkinson combiner but better efficiency. Careful attention has to pay to the amplifier impedance to stop instability that may create undesirable oscillation in the system. Analytical and ADS simulation are presented to support this work. Excellent agreement between simulations and analysis is obtained in all cases considered.

The interleaver is an important component of turbo coding and has strong impact on its error correction. The design of the NB-IoT Turbo Encoder Interleaver has a big challenge to achieve the required error correction and meet IoT applications low cost and low power constraints. In this paper, a low area interleaver is implemented to achieve the required error correction with 5% area saving by sharing resources. Sharing resources in addition to additional saving power techniques can reduce the interleaver power consumption reasonably.

This paper presents a Smart Real Time Portable Multichannel Data Logger (SRTPMDL) prototype. This system is capable of reading multiple (analog and digital) inputs through sensors while displaying data on a smart phone. The objective of this prototype is to be efficient and low cost. Examples of the inputs read are voltage, temperature, current, pressure, humidity, and digital sensors. Any of those various data types could be implemented in order to achieve our goal in monitoring industrial machines, residential homes, and other possible applications. The SRTPMDL enables to monitor remotely and to save multi analog/digital signals used to detect possible errors that might exist on specific sensors/signals.

Polar codes have been proposed recently as proven to asymptotically achieve channel capacity for memoryless channels. However, realization of high throughput decoders for large code lengths remains a daunting challenge due to the successive decoding behaviour. With the help of using radix-4 processing units, a special last stage processing unit to decode 4 bits in the same clock and partial sum look ahead technique, this paper proposes a high throughput decoder architecture, which considerably reduces the latency compared to state of the art implementations.

In this paper, we have designed and fabricated a flexible skin conductance sensor using PDMS with a minimized skin contact area and increased device flexibility. These sensors can be used for the measurement of galvanic skin response which could be used to detect emotional activity and monitor human stress in daily life. The sensor performance has been experimentally verified using the BITalino (r)evolution Board Kit. Also, a comparative study on the sticking property of PDMS with Aluminum was conducted by exposing PDMS with Oxygen and Argon Plasma. It has been found that the one treated with Argon Plasma showed better hydrophilicity and sticking properties than oxygen.

PV panels present a growing field of energy harvesting systems. New trends and problems are appearing in this technology like fire, faults, and degradations. Moreover, some behaviors are not implemented in PV simulation models like thermal behavior or degradation processes. In addition, some simulation results among researchers present divergence. In this paper we developed a test platform for PV panels in order to conduct different tests in which the inputs of the PV (Position, Irradiance, and Temperature) can be controlled.
