When interlaced scan (IS) is used for television transmission, the received video must be deinterlaced to be displayed on progressive scan (PS) displays. To achieve good performance, the deinterlacing operation is typically computationally expensive. We propose a receiver compatible approach which performs a deinterlacing operation inexpensively, with good performance. At the transmitter, the s...

Recently, there have been increasing interests to characterize the UHF wideband mobile reception. In the literature, there are several studies on UHF mobile reception for cellular phone systems, however, most of them addresses narrowband services. This paper presents propagation measurement results on UHF TV band using the ATSC Digital Television as a sounding signal to study the characteristic...

Assessment of the state health and working condition equipment in production service industries is a necessary for effective maintenance. Therefore, this work models failure times other operational characteristics television transmitter system with sudden but non-constant rate to enhance smooth operation system. The was shown follow lognormal distribution mean;

recently many studies have been done on different issues of using multiple antennas at transmit and receive sides of a radar system in a mimo (multiple input multiple output) configuration. in addition, for the electronic warfare‟s purposes, the utilization of available signals of the environment to detect the targets has gained considerable attention in recent years. such passive radars use th...

Waveguide theory is suggested for the analysis of UHF radiation in urban microcellular environments, where both the transmitter and the receiver are below rooftop level. The delay profile is calculated from the steady state power distribution among the modes of the waveguide. The delay profile is very asymmetrical because most of the power is contained in the low order (faster) modes, and becau...
