Non-coherent Detection Study for UWB Transmission and Body Area Network in Interference Environments
2020 14th International Symposium on Medical Information Communication Technology (ISMICT), 2020UWB (Ultra Wideband) modulation / demodulation systems are studied in the high band (7.25-10.25 GHz), and BER (Bit Error Rate) performances are evaluated in body area network environments. UWB-IR (UWB-Impulse Radio) pulse is transmitted by pulse position modulation (PPM) and demodulated by energy detection, where interference signals of UWB-IR ...

Diffuse Reflection and Transmission by Non-Coherently Scattering Media
Publications of the Astronomical Society of Australia, 1967It has become recognized that the dominant mechanism in the formation of the cores of resonance lines in the solar spectrum is non-coherent scattering, e.g., Thomas (1957). A study, preliminary to the theoretical investigation of the spectra of chromospheric structures, is the evaluation of the effect of diffuse reflection and transmission by non ...

Method of simultaneous transmission to coherent and non-coherent receivers using ternary sequences
2014 IEEE Global Communications Conference, 2014In this paper, we explore a method for simultaneous tranmission to coherent and non-coherent receivers, based on ternary sequences. In many communication scenarios, the transmitters are required to support both coherent and non-coherent forms of reception thereby requiring the transmission protocols to be designed such that the transmitted data is ...

System-Level Evaluation of Non-Coherent Joint Transmission in Indoor Ultra-Dense Networks
2020 International Conference on Information and Communication Technology Convergence (ICTC), 2020In recent years, an ultra-dense network (UDN) has received considerable attention as a promising technique for improving the network capacity. In this paper, we evaluate the performance of UDN with non-coherent joint transmission (NC-JT) scheme through system-level simulation including indoor UDN scenario.

A low-cost non-coherent transmission for uncoded two-way relay channels
2011 IEEE GLOBECOM Workshops (GC Wkshps), 2011In this paper, we investigate a two-phase two-way relay protocol for a scenario without channel coding or channel estimation. The considered configuration represents practical sensor networks, where the nodes wish to exchange some low rate messages (e.g.

Non-Coherent High Spectral Efficiency Long Haul Waveband Transmission
IEEE Photonics Technology Letters, 2012We introduce a waveband transmission system architecture capable of reaching 2000-km distance with a spectral efficiency of 2 bit/sec-Hz based solely on non-coherent principles and enabled by electronic equalization at the receiving end.

Pulse parity modulation for impulse radio UWB transmission based on non-coherent detection
Physical Communication, 2020Abstract To enhance the error performance of impulse radio UWB transceivers, we introduce in this manuscript a novel modulation scheme based on exploiting the symmetry properties of transmitted waveforms. Parity Modulation utilizes odd versus even pulses to represent binary data, while the detector relies on a time reverser and non-coherent cross ...

The Transmission Capacity of UWB WSN Based on Non-Coherent Detection
2011 7th International Conference on Wireless Communications, Networking and Mobile Computing, 2011The model of UWB WSN(wireless sensor networks) was proposed firstly, by UWB and non-coherent detection technology, a non-coherent detection receiver for UWB WSN was designed and the transmission capacity was studied. We found it will benefit to improve the transmission capacity of the UWB wireless sensor network if employing the non-coherent detection ...

IEEE Transactions on Wireless Communications, 2010
The generalized κ-fading model, characterized by two parameters, κ and m, is a very versatile model and was recently shown to accurately capture the effects of composite shadowing and multipath fading in wireless communication systems. Furthermore, it can be used to model cascade multipath fading, which is relevant in, e.g., mobile-to-mobile ...
