Under identical conditions, we benchmark PID against Fuzzy‐Logic control for a single‐phase H‐bridge inverter. FLC achieves faster rise/settling with lower THD and better disturbance rejection than tuned PID while requiring explicit rule design—offering a reproducible baseline and deployment guidance for power‐quality‐constrained inverter applications.

Peak Power Reduction of OFDM Signals with Sign Adjustment [PDF]
It has recently been shown that significant reduction in the peak to mean envelope power (PMEPR) can be obtained by altering the sign of each subcarrier in a multicarrier system with n subcarriers.

This work extends the Polyanskiy‐Poor‐Verdu (PPV) framework to lognormal wireless links. Specifically, the paper derives a closed‐form approximation for the average error probability under lognormal distribution, effectively generalizing the PPV analysis beyond the additive white Gaussian noise assumption.

Subcarrier and Power Allocation for LDS-OFDM System [PDF]
Low Density Signature-Orthogonal Frequency Division Multiplexing (LDS-OFDM) has been introduced recently as an efficient multiple access technique. In this paper, we focus on the subcarrier and power allocation scheme for uplink LDS-OFDM system.

Abstract In this paper, a reduced switch count single‐phase hybrid multilevel inverter (MLI) is presented. Level generation unit (LGU) and polarity changing unit (PCU) are the two parts of the presented topology which are connected in series. Other advantages of the proposed topology include the reduced switch count, higher level generation with ...

Suboptimal greedy power allocation schemes for discrete bit loading [PDF]
In this paper we consider low cost discrete bit loading based on greedy power allocation (GPA) under the constraints of total transmit power budget, target BER, and maximum permissible QAM modulation order.

Analytic cascaded filterbanks for multicarrier modulation
Filterbank multicarrier has been proposed as an alternative to rthogonal frequency division multiplexing (OFDM). A uniform Discrete Fourier Transform (DFT) transmultiplexer cannot have maximum packing efficiency while using slowly decaying pulses. Maximally decimated filterbanks and transmultiplexers can be used interchangeably.
