Multi‐path separation and parameter estimation by single DMA in fading channel.

Publication Type: Academic Journal

Source(s): IET Communications (Wiley-Blackwell). Aug2022, Vol. 16 Issue 13, p1475-1485. 11p.

Abstract: The propagation of electromagnetic waves will produce multi‐path fading of wireless channel, which degrades communication performance substantially. If multi‐path can be separated, better signal transmission and reception strategies can be designed to ...

On Polarization, Combining, and Equalization in Aeronautical Mobile Telemetry.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Aerospace & Electronic Systems. Aug2022, Vol. 58 Issue 4, p3601-3612. 12p.

Abstract: In this article, we explore the relationship between an equalizer and a combiner operating on the available polarization states of a received signal in aeronautical mobile telemetry. The maximum likelihood combiner is derived and shown to be equivalent...

Security and Reliability Performance of Noise-Loop Modulation: Theoretical Analysis and Experimentation.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Jun2022, Vol. 71 Issue 6, p6335-6350. 16p.

Abstract: Security is a crucial feature of current (5G) and even more for future (6G) communication networks. While the innate nature of the wireless channel is an issue for guaranteeing security, its physical characteristics can be exploited for protecting conf...

Joint Precoding and Pre-Equalization for Faster-Than-Nyquist Transmission Over Multipath Fading Channels.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Apr2022, Vol. 71 Issue 4, p3948-3963. 16p.

Abstract: Faster-than-Nyquist signaling (FTNS) has emerged as a promising technique to increase communication capacity in bandwidth-limited channels. However, the presence of FTN-induced inter-symbol interference (FTN-ISI) in the received observations, is detrim...

PLC Physical Layer Link Identification with Imperfect Channel State Information.

Publication Type: Academic Journal

Source(s): Energies (19961073). Aug2022, Vol. 15 Issue 16, p6055-N.PAG. 19p.

Abstract: This paper proposes an accurate physical layer technique to uniquely identify the links of a power line communication network. First, the power line communications (PLC) multipath channel characterization is presented and detailed. Then, a multipath ch...

Low CP Overhead Waveform Design for Multi-Path Channels with Timing Synchronization Error.

Publication Type: Academic Journal

Source(s): Sensors (14248220). Aug2022, Vol. 22 Issue 15, p5772-N.PAG. 21p.

Abstract: In classical orthogonal frequency division multiplexing (OFDM) systems, inserting the cyclic prefix (CP) is necessary before each symbol to overcome the multi-path effect, which, however, occupies numerous time-frequency radio resources, resulting in h...

Stochastic Fading Channel Models With Multiple Dominant Specular Components.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Mar2022, Vol. 71 Issue 3, p2229-2239. 11p.

Abstract: We introduce a comprehensive statistical characterization of the multipath wireless channel built as a superposition of scattered waves with random phases. We consider an arbitrary number $N$ of specular (dominant) components plus an undetermined numbe...

The Impact of Multipath Information on Time-of-Arrival Estimation.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Signal Processing. 2022, Vol. 70, p31-46. 16p.

Abstract: Time-of-arrival (TOA) based localization plays a central role in current and future localization systems. Such systems, exploiting the fine delay resolution properties of wideband and ultra-wideband (UWB) signals, are particularly attractive for rangin...
