The absolute phase is the accumulated phase change over an observation interval. It is a new variable for the mobile channel and can be simply derived from the wrapped phase or from the quadrature components. The absolute phase offers extra information about the channel, fostering new techniques for channel characterization and location estimation. However, the absolute phase has not been used in...
In this paper, shadow fading (SF) in an indoor multipath environment is measured and the spatial correlation of SF is modeled statistically. To effectively extract SF from the measured field strength, we use frequency averaging (FA) method instead of spatial averaging (SA) method which has generally been used. SF is modeled as a random variable with a log-normal distribution. The spatial correlation...
Various terrestrial digital television broadcasting standards have been developed in the last two decades for both fixed residential and mobile receivers. Since personal mobile terminal integrated with multiple functionalities is becoming more popular, it is highly desirable to come up with a universal platform for mobile TV reception which can detect the system parameters of DTV signals automatically...
Mobile terminals used in the stationary condition experience a level variation different from that found in the moving condition. Therefore, it is very important to study the fading characteristics of static usage. This paper clarifies the generalized fading characteristics of mobile terminals in outdoor NLOS environments when they are used in the stationary condition; only adjacent objects such as...
