Sentence examples for mobile radio environment from inspiring English sources

The performance of OFDM has largely been investigated in the mobile radio environment.

In the mobile radio environment, this variation is due to the Doppler effect and is quantified by means of the so-called Doppler spread [22].

Techniques have also been proposed to use the characteristics of the radio channel itself to provide secure key distribution in a mobile radio environment, where the information bearing signal is modified to precompensate for the phase effects of the channel [6].

This work has investigated the application of a belief-based approach, the Dempster-Shafer theory, to the problem of computing spectrum occupancy maps for heterogeneous mobile radio environments.

The proposed scheme allows for joint estimation of the relative delay, the direction (i.e. azimuth and co-elevation) of departure, the direction of incidence, the Doppler frequency and the polarization matrix of propagation paths between the transmitter and receiver sites in mobile radio environments.

Therefore, in this study, a physical layer interference model in a mobile radio communication environment is investigated by taking into account all of the basic propagation mechanisms such as large- and small-scale fading under a generic single primary user (PU) and single secondary user (SU) scenario.

In a mobile, heterogeneous radio environment, where the demands on spectrum in a given location change with time, a more dynamic approach to spectrum management may be able to make more effective use of the band and support higher user throughput.

This provides a benign environment for the mobile radio provision.

In this article, cognitive Doppler spread compensation algorithms are proposed for high-speed rail broadband mobile communications, which make use of the dedicated radio environment map (REM) for railway to compensate the time-varying Doppler spread.

To mitigate the adverse impact of time-varying Doppler spread on OFDM-based broadband mobile communications, this article proposes cognitive Doppler compensation algorithms based on dedicated radio environment map (REM) for high-speed rail.

The properties also include paging and mobile radio operations.
