LoRaWAN is a prominent communication standard to enable reliable low-power, long-range communications for the Internet of Things (IoT). The modulation technique used in LoRaWAN, commonly known as LoRa modulation, based on principle chirp spread spectrum (CSS). main objective this article design practical, low-complexity coherent receiver recently proposed CSS-based scheme, called phase-shift ke...

Microwave backhaul links are characterized by high signal-to-noise ratios permitting spectrally-efficient transmission. The used signal constellation sizes and achievable data rates typically limited transceiver impairments, predominantly phase noise from non-ideal carrier generation. In this paper, we propose a new method to improve the rate over such microwave links. We make use of fact that ...

This paper presents a new spectrum-sharing strategy based on spatial information about mutual interference constraints, temporal spectrum usages and positions of devices. This strategy can solve the coexistence problem of Cognitive Radio (CR) networks and simplify the design of CR devices. In fact, it is a crosslayer design strategy that integrates useful information obtained from the physical,...

In recent years, such small body exploration missions as asteroids or comets have received remarkable attention in the world. In small body explorations, especially, detailed in-situ surface exploration by tiny rover is one of effective and fruitful means and is expected to make strong contributions towards scientific studies. JAXA/ISAS is promoting MUSES-C mission, which is the world’s first s...

We presents a refined multiscale Shannon entropy for analyzing electroencephalogram (EEG), which reflects the underlying dynamics of EEG over multiple scales. The rationale behind this method is that neurological signals such as EEG possess distinct dynamics over different spectral modes. To deal with the nonlinear and nonstationary nature of EEG, the recently developed empirical mode decomposi...

Today, cellular services include voice, short message service, and fax transmission. In the future, cellular will be moving towards multimedia applications, incorporating high speed data and video transmission. These services impose di erent demands in terms of quality and data rate on the system. In addition frequency planning becomes more and more complex as cell size decreases. CDMA seems to...
