A simple approach for adaptive interference suppression for the downlink (base-to-mobile link) of a direct sequence (DS) based cellular communication system is presented. The base station transmits the sum of the signals destined for the different mobiles, typically attempting to avoid intra-cell interference by employing orthogonal spreading sequences for different mobiles. However, the signal...

There is a basic constraint imposed on radar measurements when the transmitted signal is a simple, CW pulse. As a result, the radardesigner may wish to use a more complex signal and thereby extract more information from an echoing object. Unfortunately, the processed returns of the sophisticated waveforms usually consist of a peak response and small adjacent responses (called "time sidelobes") ...

The problem of channel shortening equalization for optimal detection in ISI channels is considered. The problem is to choose a linear equalizer and a partial response target filter such that the combination produces the best detection performance. Instead of using the traditional approach of MMSE equalization, we directly seek all equalizer and target pairs that yield optimal detection performa...

Decision feedback equalizer uses prior sensor’s decisions to mitigate damaging effects of intersymbol interference on the received symbols. Due to its inherent non linear nature, decision feedback equalizer outperforms the linear equalizer in case where the intersymbol interference is sever in a communication system. Equalization of multiple input multiple output fast fading channels is a daunt...

The recent digital transmission systems impose the application of channel equalizers with short training time and high tracking rate. Equalization techniques compensate for the time dispersion introduced by communication channels and combat the resulting inter-symbol interference (ISI) effect. Given a channel of unknown impulse response, the purpose of an adaptive equalizer is to operate on the...

This paper presents some results and conjectures dealing with channel equalization. For several possible equalizers, the following question is considered: if the equalizer output sequence has identical statistics to the input signal sequence, has the equalizer correctly converged? 1. THE PROBLEM DOMAIN Many communication signal processing problems envisage a transmitted sequence a0 a1, ... draw...

Abstract The process of parametric equalization musical pieces seeks to highlight their qualities by cutting and/or stimulating certain frequencies. In this work, we present a neural model capable equalizing song according the genre that is being played at given moment. It normal (1) should adapt throughout and not always be same for whole song; (2) songs do belong specific may contain touches ...

The energy flow is step-by-step among Lithium-ion-battery when an equalizer based on the buck-boost converter adopted, resulting in a long transmission path and low equalization efficiency. First, dual active half-bridge studied this paper. Second, key parameters of between cells same group different groups are analyzed. Third, phase shift control strategy put forward according to analysis resu...
