in this paper, a ground early warning receiver is introduced and explained for the reception and monitoring of signal from a space-borne synthetic aperture radar. this receiver can be used for various electronic warfare applications and implemented in two sectors of time parameter detector and frequency parameter detector. it can measure power, bandwidth, central frequency, pulse width, pulse r...

| Linear minimum mean squared error (LMMSE) criterion can be used to obtain near-far resistant single-user receivers in direct-sequence code-division multiple-access (DS-CDMA) systems. A mod-iied version of the receiver, called LMMSE-RAKE receiver , has previously shown promising performance in frequency-selective fading channels. In this paper, both the convergence and BER performance of an ad...

The vulnerability of civil GPS receiver to interference may be intentional or unintentional. Among all types of interference, replay attack intended as the most dangerous intentional one. The signal structure of replay attack is almost the same with the satellite signal. The interference effects can be reduce with the design of an appropriate filter in the receiver. This paper presents two meth...

Abstract A novel equalizer for single carrier Digital Television Terrestrial Broadcasting system is proposed. Because of the state-of-art equalization normally uses frequency domain DFE scheme, herein, we suggested combining with a maximum ratio combing (MRC) receiver diversity block and accordingly a frequency domain maximum ratio combing decision feedback filter (FD-MRC-DFE) structure is obta...

This paper analyzes the spectral efficiency (total channel capacity per subband) of randomly-spread synchronous multicarrier code-division multiple-access (MCCDMA) channel subject to frequency-selective fading in the asymptotic regime of number of users and bandwidth going to infinity with a constant ratio. We analyze the spectral efficiency for uplink and downlink conditioned on subcarrier fre...
