This paper describes a technique to ghosts cancellation without a Ghost Cancellation Reference signal. The existing vertical edges in TV image are used to estimate the channel characteristics. With the estimating results, the coefficients of the equalizer are updated. In this paper, a method to speed up the convergence is given. The equalizer structure for(More)
In this paper, multiantenna scanning diversity system is used to combat fading for mobile reception of video signals. Based on the principle of the multiantenna scanning diversity system, a new approach to select the strongest signal every TV line is developed. Principle to adaptive weighting all the received antenna signals is also presented. A blind(More)
In this paper we present an approach to equalize multipath transmitted video signals without any reference signal. This approach takes advantage of the constant envelope feature of the color burst signal, which is transmitted in the blanking interval of each TV line and can be considered as an angle-modulated signal. The constant modulus algorithm (CMA)(More)
