Orthogonal matched filter detection

In this paper we consider the generic problem of detecting a transmitted signal when one of M known signals is transmitted. Instead of using a classical matched filter (MF) detector, matched to the transmitted signals, we propose using an orthogonal matched filter (OMF) detector, which is matched to a set of orthogonal signals that are closest in a least-squares sense to the transmitted signals...

Orthogonal and projected orthogonal matched filter detection

This paper considers the generic problem of detecting in the presence of additive noise, which one from a set of known signals has been received. In place of the classical matched #lter (MF) receiver we propose a modi#ed receiver. When the transmitted signals are linearly independent this receiver is referred to as an orthogonal matched #lter (OMF) receiver, and when the transmitted signals are...

Fast communication Orthogonal multiuser detection

In this paper we propose a new linear multiuser detector for synchronous CDMA systems. Speci.cally, the received signal is demodulated using an orthogonal multiuser (OMU) receiver that is matched to a set of orthogonal vectors that are closest in a least-squares sense to the signature vectors. We show that this approach is equivalent to optimally whitening the noise component in the output of t...

Matched Filter Bound Optimization for Multiuser Downlink Transmit Beamforming

This paper is devoted to the optimization of the matched filter bounds (MFB) of different co-channel users, using adaptive antenna arrays at base stations for downlink transmit beamforming in cellular mobile communication systems. We mainly consider time division multiple access (TDMA) frequency division duplex (FDD) based systems. Note that in the case of time division duplex (TDD), under cert...

cauchy based matched filter for retinal vessels detection

in this paper, a novel matched filter based on a new kernel function with cauchy distribution is introduced to improve the accuracy ofthe automatic retinal vessel detection compared with other available matched filter‑based methods, most notably, the methods builton gaussian distribution function. several experiments are conducted to pick the best values of the parameters for the new designedfi...
