Receivers of broadcast digital television (DTV) service operate in an often difficult environment of electrical interference, multiple other TV signals in close frequency proximity, multipath, wide dynamic range input signals, and uncertain antenna c

We analyze a blind channel impulse response identification scheme based on the cross correlation of blind symbol estimates with the received signal. The symbol estimates specified are those minimizing the Godard (1980) (or constant modulus) criterion

In the noise-free case, the fractionally spaced equalization using constant modulus (FSE-CM) criterion has been studied previously. Its minima were shown to achieve perfect equalization when zero-forcing (ZF) conditions are satisfied and to be able t

The vector-constant modulus (VCM) criterion is an extension of the constant modulus (CM) criterion introduced recently for equalization of channels involving Gaussian sources. In this letter, we analyze the behavior of VCM for arbitrary source distri

We present a new robust backward compatible 8-VSB transmission system for HDTV terrestrial broadcast. The new transmission system allows better reception of signals for portable, mobile and indoor receivers. In the proposed system a scalable fraction

A new enhanced VSB (E-VSB) transmission system has been proposed to improve the North-American HDTV terrestrial broadcast. The system allows better reception for portable, mobile, and indoor receivers, by means of two backward compatible robust and s

For pt.1 see ibid., p.116-17 (2003).This second part of the paper motivates the use of adaptive estimation of the DC offset at the receiver and gives an interpretation of the result furnished by a joint optimization over the DC offset estimate and th

Existing methods for blind channel equalization that explicitly use channel diversity lead either to estimation of a single equalizer (without control of the transmission delay) like linear prediction or to estimation of all equalizers associated to
