Adaptive Equalization of the Slow Fading Channel

Introduction to spread-spectrum antimultipath techniques and their application to urban digital radio

“…When passed through this nonlinearity, the Jth envelope detector output of The waveform of Fig. 9 illustrates a certain self-adaptivity implicit in (17). A priori, path delays are unknown.…”

“…The output of the nonlinearity thus presents data that are heavily adjusted by a posteriori evidence of the existence of paths. As shown by (17), these data are further weighted by the a priori knowledge of the probabilities of path occurrences implicit in the function p(-).…”

Stochastic Approximation with Correlated Data

“…2), one obtains 12) Recall that the matrix norm for a p x p matrix A is defined by Chapter II are given in Section tV-B.…”

“…The output of this second transversal filter is fed back into the input of the quantizer . Monsen [12] presents a performance comparison of decision feedback and linear equalizers.…”

A Suboptimal Receiver with Turbo Block Coding for Ultra-Wideband Communications

“…It is also well known that an alternative approach to reduce the complexity of the VE solution is the use of adaptive equalization techniques [8]- [10]. At the cost of a performance loss, the complexity of adaptive equalizers is a linear function of J. Consequently, it becomes of practical interest to study the performance of adaptive equalizers in UWB communications.…”
