چکیده

This paper concerns PN signal detection in multipath interference by using a passive correlation receiver with an OS CFAR processor. Noise level estimation is performed in both windows, using the ordered statistics (OS) approach. The minimum of the average decision threshold is used as an OS estimation criterion of effectiveness [1] The CFAR processor parameters are obtained by Monte Carlo simulation. The achieved results can be applied for target detection in multistatic radars using existing communication networks.

PN Code Acquisition Using Smart Antenna and Adaptive Thresholding CFAR Based on Ordered Data Variability for CDMA Communications

Recently, a novel approach for PN code acquisition of direct sequence code division multipleaccess (DS-CDMA) systems in Rayleigh fading multipath channel was proposed in [1]. The authors considered a combination of adaptive thresholding constant false alarm rate (CFAR) and smart antennas to increase the system capacity and consequently enhance the detection performance. This paper considers sti...

A High-Resolution Detector in Multipath Environments

In this paper we introduce a high-resolution CFAR detector for the linear data model. The detector is derived using the generalized likelihood-ratio test (GLRT) framework. The resulting detector has a number of distinctive properties. One property of the detector is that it is most useful when the training and testing data contain the signal-of-interest. In fact, this detector does not need tra...

Adaptive Signal Detection in Auto-Regressive Interference with Gaussian Spectrum

A detector for the case of a radar target with known Doppler and unknown complex amplitude in complex Gaussian noise with unknown parameters has been derived. The detector assumes that the noise is an Auto-Regressive (AR) process with Gaussian autocorrelation function which is a suitable model for ground clutter in most scenarios involving airborne radars. The detector estimates the unknown...

Novel receiver signal processing for interference cancellation and equalization in cellular TDMA communication

A space-time processing scheme is proposed for TDMA based cellular/PCS communications that cancels co-channel interference while simultaneously equalizing the desired signal. This is achieved through processing of a training signal designed from a PN code. At the receiver, the symbol waveform is built up above the noise and interference through correlation with a sampled waveform designed to ex...
