Short range unlicensed radio links, with typical ranges of 1 to 100 meters, are becoming more and more popular. Millions of these radios are used today in such applications as automotive keyless entry, tire pressure monitoring, gate openers, wireless security systems, data links, remote meter reading and too many other applications to enumerate. With the number of short range devices (SRD’s) in...

In recent years, CDMA has been recognized as one of the most efficient and reliable schemes for cellular radio communications. The CDMA scheme was adopted as a new wireless communication industry standard, IS-95,1 by the Electronic Industries Association (EIA) and the Telecommunications Industry Association (TIA) in 1993 and possesses several distinct advantages:2 The spectral density is reduce...

Aspect Oriented Modeling separates crosscutting concerns by defining Aspects and composition mechanisms at the model level. Composition of multiple Aspects will most likely result in more than one Aspect matching the same join points. Consequently, Aspects do not always interact in a predictable manner when woven together. Intended interaction among aspects is designed by the system designer. U...

The E. & F. White Conference held in Sydney in December 1999 brought together expertise on a range of interference mitigation techniques from CSIRO, Australian and international industry and universities. Key goals were to enhance the understanding of techniques and their inter-relationship, to increase awareness of advanced technologies such as software radios and photonics, and to foster a co...

Multi-antenna non-orthogonal multiple access (NOMA) is a promising technique to significantly improve the spectral efficiency and support massive access, which has received considerable interests from academic and industry. This article first briefly introduces the basic idea of conventional multi-antenna NOMA technique, and then discusses the key limitations, namely, the high complexity of suc...

In the last decade, Time-of-Flight (ToF) range cameras have gained increasing popularity in robotics, automotive industry, and home entertainment. Despite technological developments, ToF cameras still suffer from error sources such as multipath interference or motion artifacts. Thus, simulation of ToF cameras, including these artifacts, is important to improve camera and algorithm development. ...

The Cognitive Neuroscience Treatment Research to Improve Cognition in Schizophrenia (CNTRICS) meeting on "Selecting Promising Animal Paradigms" focused on a consideration of valid tasks for drug discovery in non-humans. This consensus review is based on a break-out session with experts from academia and industry which considered tasks that tap working memory in animals. The specific focus of th...

The adoption of LoRaWAN as a technology for wireless deployments in many applications, such smart cities or industry 4.0, still presents challenges energy consumption, robustness, reduced throughput harsh, noisy scenarios. Class B is MAC mode that allows better performance downlink traffic but has difficulties regarding scalability and its response to channel interference. This article introduc...

Effective interference management has been recognized by the industry and standardization bodies as a key enabler for 4G systems. This work is about static Inter-Cell Interference Coordination for OFDMA based cellular networks such as LTE. The majority of previous ICIC studies, both theoretical and simulation-based, have been conducted considering synthetic and/or small cellular layouts. In thi...

Rapid growth in telecom industry searching for new methods provide the better service to their customer here implementing proposes a multihop dynamic channel assignment (MDCA) scheme for time division multiple access (TDMA)-based multihop cellular networks. The proposed MDCA assigns channels are observed in ofdma system to the calls based on interference information in surrounding cells, provid...
