Essential tremor is a disorder that causes involuntary oscillations in patients both while they are engaged in actions and when maintaining a posture. Such patients face serious difficulties in performing daily living activities such as meal movement. We have been developing an electromyogram (EMG)-controlled exoskeleton to suppress tremors to support the movements of these patients. The proble...

The extended binary phase shift keying (EBPSK) is an efficient modulation technique, and a special impacting filter (SIF) is used in its demodulator to improve the bit error rate (BER) performance. However, the conventional threshold decision cannot achieve the optimum performance, and the SIF brings more difficulty in obtaining the posterior probability for LDPC decoding. In this paper, we con...

We present how the laser diode (LD) current tuning induced intensity modulation affects the performance of an open-loop resonator fibre optic gyro (R-FOG) with sinusoidal wave modulation. The expression for the demodulation curve under intensity modulation caused by the dynamic input rotation angular rate and varied environmental factors induced resonance frequency drift is provided. Numerical ...

The discrete multitone (DMT) modulation/demodulation scheme is the standard transmission technique in the application of asymmetric digital subscriber lines (ADSL) and very-high-speed digital subscriber lines (VDSL). Although the DMT can achieve higher data rate compared with other modulation/demodulation schemes, its computational complexity is too high for costefficient implementations. For e...

1 Abstract In our software-defined radio project we have implemented two different types of standards, a continuousphase-modulation (CPM) based standard, Bluetooth, and an OFDM based standard, HiperLAN/2, on a generalpurpose processor. First we describe our baseband software-defined radio testbed for the physical layer of wireless LAN standards. All physical layer functions have been successful...

This article presents an enhanced frequency adaptive demodulation technique for grid-synchronization of grid-connected converters in variable condition. Demodulation works by generating demodulated voltages which contain undesired double components. As a result, high-order low-pass filters with high cutoff are required to eliminate the reduces dynamic performance. Frequency enhances performance...
