Exploiting Cyclic Prefix in Turbo FDE Systems Using Factor Graph

, 2013
This paper investigates the MMSE-based frequency domain equalization (FDE) algorithms in turbo equalization systems. As opposed to the conventional FDE systems where the cyclic prefix (CP) is discarded at the receiver, we take advantage of the redundancy

A comparison between OFDM and SC-FDE over wideband satellite downlinks

, 2020
Single Carrier Frequency Domain Equalization (SC-FDE), has recently attracted significant interest particularly in the wireless communications literature as an alternative air-interface solution to OFDM.

A Neutral FDE Is Similar to the Product of an ODE and a Shift

Journal of Mathematical Analysis and Applications, 1995
Neutral functional differential equations of the form \(x'+ \alpha * x+ \beta* y= f\), \(\gamma * x+ \mu* y= g\), \(x(0)= \xi\); \(x= \phi\), \(y= \psi\) on \(\mathbb{R}^-\), are considered. It is first shown that the equation is well-posed with \(\alpha\), \(\beta\), \(\gamma\) and \(\mu\) locally finite matrix-valued measures if and only if \(\mu ...

Block Iterative FDE for MIMO Underwater Acoustic Communications

, 2016
In this paper, we propose a low complexity iterative detection scheme for the uncoded zero padding (ZP) single carrier (SC) transmission in Multiple-input Multiple-output (MIMO) underwater acoustic (UWA) channels.

Combined MMSE-FDE and Interference Cancellation for Uplink SC-FDMA with Carrier Frequency Offsets

, 2010
Due to its lower peak-to-average power ratio (PAPR) compared with orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA) has been recently accepted as the uplink multiple access scheme in the ...
