Polarization of Ionospherically Propagated HF Radio Waves with Applications to Radio Communication
Radio Science, 1969Sweep‐frequency CW radio signals transmitted over 1300‐km north‐south and 1900‐km east‐west temperate‐zone paths were received 24 hours per day for 21½ ‐day periods. Measurements of the incoming one‐hop F‐layer polarization, as a function of time‐of‐day and radio frequency, indicate that daytime rates of change of polarization rotation with frequency ...

4th National Conference of Telecommunication Technology, 2003. NCTT 2003 Proceedings., 2003
It is well known that the propagation characteristics are changed for wireless communication. We have investigated the characteristics of radio wave for indoor wireless communication in a typical Malaysian office environment. It is not too far when a lot of Malaysian people will use their personal computer or lab top in the office for signal ...

2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009
In order to minimize infection risks of patients with artificial hearts, wireless data transmission methods with electromagnetic induction or light have been developed. However, these methods tend to become difficult to transmit data if the external data transmission unit moves from its proper position.

Radio Wave Interference Test Method for Wireless Communication System by Opened Parallel Wired Cell
IEICE Transactions on Communications, 2005We have studied on the interference test method from IEEE802.11b to IEEE802.11g as an interference source with wide band spectrum by using the opened PW cell, and it is clear that the throughput of IEEE802.1 Ig for only IEEE802.11b Ch.4 signal wave as the interference wave, whose frequency spectrum is almost not overlapping with IEEE802.11g, is almost ...

Measured inhouse radio wave propagation characteristics for wideband communication systems
8th European Conference on Electrotechnics, Conference Proceedings on Area Communication, 2003The frequency-selective radio-wave propagation characteristics for in-house communication systems are statistically characterized for the cases of line-of-sight and obstructed path propagation. Using the theory of random time-variant linear filters, it is found that the RMS (root mean square) delay spread, the Doppler spread and coherence time, the ...

AbstractObjectiveAboriginal people experience a higher burden of disease as a consequence of drug and alcohol (D&A) abuse. Although media campaigns can be a popular tool for disseminating health promotion messages, evidence of the extent to which they reduce the impact of substance abuse is limited, especially for rural Aboriginal communities. This

The propagation of radio waves through the atmosphere of the Earth finds a wide range of applications for science and engineering. Among the scientific application areas we name ionospheric physics, radio astronomy, space geodesy and oceanography. The engineering applications span such diverse areas as communication, navigation and time dissemination ...

Keynote address: Engineering radio waves for future wireless communication and biomedical systems
2016 Moratuwa Engineering Research Conference (MERCon), 2016Radio-frequency waves, including microwaves, play a crucial role in current wireless systems, both communication and biomedical. Millimetre-waves are being seriously considered for the next-generation (5G and beyond) communication systems because the expected improvement in throughput cannot be achieved only from improvement to coding and other “soft ...
