Harmonic Rejection Exploiting Adaptive Interference Cancellation
Wideband direct-conversion harmonic-rejection (HR) receivers for softwaredefined radio aim to remove or relax the pre-mixer RF filters, which are inflexible, bulky and costly [1,2]. HR schemes derived from [3] are often used, but amplitude and phase mismatches limit HR to between 30 and 40dB [1,2]. A quick calculation shows that much more rejection is wanted: in order to bring harmonic response...
متن کاملA Blind Interference Canceling Technique for Two-Stage Harmonic Rejection in Down-mixers
This paper presents practical experiments on a harmonic rejection down-mixer, which offers up to 75 dB of harmonic rejection, without an RF filter. The down-mixer uses a two-stage approach; the first stage is an analog multi-path/multiphase harmonic rejection mixer followed by a second stage providing additional harmonic rejection based on blind adaptive interference canceling in the discrete-t...
متن کاملA maximum likelihood approach to blind multiuser interference cancellation
This paper addresses the problem of blind multiple access interference (MAI) and inter-symbol interference (ISI) suppression in direct sequence code division multiple access (DS CDMA) systems. A novel approach to obtain the coefficients of a linear receiver using the maximum likelihood (ML) principle is proposed. The method is blind because it only exploits the statistical features of the trans...
متن کاملAdaptive Blind Interference Cancellation in Cdma Systems
Multiuser CDMA communication systems experience multiple access interference as well as multipath distortions and require some interference cancellation scheme at the receiver. While blind multiuser receivers have received considerable attention, adaptive versions are often limited to the no multipath case. In this paper, the receiver’s output variance is minimized subject to appropriate constr...
متن کاملTwo-stage Approach for Multichannel Blind Deconvolution
Multichannel blind deconvolution is a method that allows the separation of sources from which only convolutive mixtures are observable. It is an attractive technique for separating independent speech and noise signals. Fast tracking is essential in order to cope with real nonstationary environments. Based on the principle of information maximization, a new two-stage algorithm is proposed which ...
