Digital Compensation of Distortion in Audio Systems (Electronics Project)

The advancements of computational power in low cost FPGAs are giving the opportunity to implement real-time compensation of loudspeakers and audio systems. This project aims at evaluating methods for digital compensation of distortion in audio systems. The need for expensive commercial audio systems is reduced when the fidelity of much cheaper audio systems easily can be improved by real-time compensation. […]

Efficient Key Generation by Exploiting Randomness From Channel Responses of Individual OFDM Subcarriers (IEEE Electronics Project)

Key generation from the randomness of wireless channels is a promising technique to establish a secret cryptographic key securely between legitimate users. This paper proposes a new approach to extract keys efficiently from the channel responses of individual orthogonal frequency-division multiplexing (OFDM) subcarriers. The efficiency is achieved by: 1) fully exploiting randomness from time and frequency domains and 2) improving […]

Multi-label Classification Methods for Green Computing and Application for Mobile Medical Recommendations (IEEE Computer Project)

With the explosive development of communication technologies, more customer friendly services have been designed for the next generation of cellular technology, that is, fifth-generation (5G) communication. However, such services require more computing resources and energy. Thus, the development of green and energy-efficient 5G application systems has become an important topic in communications. In this paper, we focus on high-performance multi-label […]

Virtual RC Damping of LCL-Filtered Voltage Source Converters With Extended Selective Harmonic Compensation (IEEE Electrical Project)

Active damping and harmonic compensation are two common challenges faced by LCL-filtered voltage source converters. To manage them holistically, this paper begins by proposing a virtual RC damper in parallel with the passive filter capacitor. The virtual damper is actively inserted by feeding back the passive capacitor current through a high-pass filter, which indirectly, furnishes two superior features. They are […]

Audio DSP: Time and Frequency Varying Gain Compensation for Non-Optimal Listening Levels (Electrical/Electronics Project)

Although the human hearing system is very complex, several models exist that explain parts of the hearing system. This study uses one of these models, the contours of equal loudness, to make music played at low listening levels sound more like it does at the intended listening level. The perceived frequency balance of music varies with the listening level. This […]
