A typical geoacoustic inversion procedure involves powerful source transmissions received on a large-aperture receiver array. A more practical approach is to use a single moving source and/or receiver in a low signal to noise ratio (SNR) setting. This paper uses single-receiver, broadband, frequency coherent matched-field inversion and exploits coherently repeated transmissions to improve estim...

In this paper, we propose a novel iterative transmit/receive equalization technique for single-carrier (SC) block transmission in a severe frequency-selective fading channel. Iterative frequency-domain intersymbol interference (ISI) cancellation (FDIC) is introduced to the previously proposed joint iterative transmit/receive frequency-domain equalization (FDE) based on the minimum mean square e...

In this paper, we propose a low complexity receiver structure for Single-input Multiple-output (SIMO) downlink cyclic prefix CDMA (CP-CDMA) systems. It employs an interference cancellation scheme to suppress the interference caused by the multipath fading channel. Also, the proposed scheme is developed for Multiple-input Multiple-output (MIMO) CP-CDMA system. All filters in the proposed receive...

The Universal Filtered Multicarrier (UFMC) waveform technology is one of the promising waveforms for 5G and beyond networks. Owing 2N-point Fast Fourier Transform (FFT) processor at UFMC receiver, computational implementation complexity two times more than conventional Orthogonal Frequency Division Multiplexing (OFDM) receiver system. In this paper, we proposed a simplified structure to reduce ...

This paper investigates how to take advantage of the known position of a point at which a single frequency GPS receiver is located. Using this reference point and a single frequency receiver, a precise relative positioning method is developed. This method is particularly suited for the applications whose accuracy requirements are relaxed as time passes. In some circumstances, one requires a far...
