A High Efficiency Wind Energy System

A Novel Wireless Fire Alert System Using Harmony Search Algorithm

In today’s world,we are fazed by different types of emergencies in the indoor environment .One such emergency is fire outbreak. Thus, reliable and quick detection of fire is essential. Most prevalently used technology for this purpose is wireless sensor networks(WSN). A system is proposed that enables practical development of centralized cluster-based protocols supported by optimization methods...

A high-efficiency hybrid high-concentration photovoltaic system

Photovoltaic power generation is a growing renewable primary energy source, expected to assume a major role as we strive toward fossil fuel free energy production. However, the photovoltaic efficiencies limit the conversion of solar radiation into useful power output. Hybrid systems extend the functionality of concentrating photovoltaics (CPV) from simply generating electricity, to providing si...

High-Efficiency L-band Transmitmeceive Module for Synthetic Aperture Radar

Space-based radar places significant demands on the spacecraft resources (mass, power, data rate) and is therefore very expensive to implement. These systems typically require active phased-array antennas with hundreds or thousands of Transmit/Receive (TIR) modules distributed on the array. Highefficiency is a vitally important figure of merit for the radar T/R module because it reduces the pow...

A Novel BICM-ID System Approaching Shannon-Limit at High Spectrum Efficiency

A method to construct bit-interleaved coded modulation with iterative demapping and decoding (BICM-ID) is developed that approaches the Shannon limit very closely at high spectrum efficiency, where amplitude-phase shift keying (APSK) constellations are designed and chosen. For 1/2-rate 64APSK, the Es/N0 threshold derived through extrinsic information transfer (EXIT) charts is less than 0.55 dB ...
