Two existing blind equalization tap update recursions for 64-point and greater QAM
(quadrature amplitude modulation) signal constellations are studied, along with existing and …

Designing matched transmit and receive filters whose combination satisfies the Nyquist
condition is a classical problem in digital communication systems. In this correspondence …

An improved linear programming algorithm is required for the design of finite impulse
response (FIR) digital filters. This algorithm avoids the numerical ill-conditioning problems …

In this paper new pulse shapes of multicomponent signals are presented to improve spectral
efficiency. We propose a solution to an optimization problem for obtaining optimal pulse …

The problem of optimum FIR energy compaction filter design for a given number of channels
M and a filter order N is considered. The special cases where N< M and N= 1 have …

Fast initial training of a voiceband data-modem receiver which employs an equalizer with
fractionl-T spaced coefficients is presented. The modem receiver performs rapid gain …

Bandwidth efficiency is a key objective in the design of a digital communication system.
Traditionally it is accomplished by increasing the constellation size of the signaling system …
