New modified carrier‐based level shifted pulse width modulation approaches for single‐phase trinary dc source fed cascaded H‐bridge inverters are proposed in this article. In order to suppress the lower order harmonics, the carrier frequency is often tuned higher. However, switching and electromagnetic interference problems have a significant influence

This article presents a dual‐source novel nine‐level inverter (DSN2LI) featuring minimal devices. Utilizing eight switches, which include 2 bidirectional switching devices and 2 uneven dc links, the proposed DSN2LI generates nine levels. The DSN2LI employs the utilization of trinary geometric DC links.

UEP Concepts in Modulation and Coding
First unequal error protection (UEP) proposals date back to the 1960's (Masnick and Wolf; 1967), but now with the introduction of scalable video, UEP develops to a key concept for the transport of multimedia data.

The proposed TB‐SCMLI is able to provide seven levels of output voltage by balancing the voltage of two capacitors with the given control logic. The various SCMLIs are evaluated to determine the contribution of the suggested TB‐SCMLI topology's merits and downsides.

High peak-to-average power ratio (PAPR) is one of the common drawbacks of multicarrier signals at the transmitter. In this paper, we investigate the PAPR reduction of spectral efficient multicarrier faster-than-Nyquist (MFTN) signals, where the PAPR ...

Throughput Analysis of Wavelet OFDM in Broadband Power Line Communications
Windowed orthogonal frequency-division multiplexing (OFDM) and wavelet OFDM have been proposed as multicarrier techniques for broadband communications over the power line network by the standard IEEE 1901.

This article presents an analysis of the reconstructed modulators modulation strategy, a technique designed for energy balancing in DC‐to‐AC converters. The study evaluates the performance of this strategy, applied to a seven‐level multilevel cascade inverter. ABSTRACT This paper presents an experimental evaluation of a PWM modulation strategy based on
