DPD systems are a type of emissions control system common on newer trucks. They’re also called DPF (diesel particulate filter) systems. They are designed to remove diesel particular matter (soot) from the exhaust gas in a diesel engine.

A diesel particulate diffuser, or DPD, is an emission control device used in diesel engines to reduce the amount of particulate matter (PM) emissions released into the atmosphere – they lower exhaust emissions. They’re also called DPF (diesel particulate filter).

Isuzu's DPD (Diesel Particulate Diffuser) was introduced in 2017 on their 4JJ1 engines for their D-Max and MU-X vehicles. The DPD system which is made up of a DOC (Diesel Oxidation Catalyst)...

Welcome to DPD. DPD is part of Geopost, one of the world leading parcel delivery networks operating in more than 50 countries. Our 57,000 delivery experts deliver more than 8 million parcels worldwide each day through the brands DPD, Chronopost, SEUR, BRT, …

Facing the severe power consumption and energy efficiency challenges in 5G era, a novel DPD solution enabled by deep learning and big data is proposed. This is a flexible system suitable for various wireless network architectures and diverse application scenarios.

RNAV2 Precision Navigation System (p/n 4600-101) is an innovative electronic navigation system that can be either mounted in the DPD to enable precision navigation by combat divers, or without divers for Optionally-Manned Vehicle (OM2) missions.

In this article, we propose a novel technique of digital predistortion (DPD) for dual-band power amplifiers (PAs) based on the periodically nonuniform sampling (PNS) theory.

DPD is one of the most cost-effective linearization techniques. It features an excellent linearization capability, the ability to preserve overall efficiency, and it takes full advantage of advances in digital signal processors and A/D converters.

2022年4月6日 · 数字预失真（DPD）是目前 无线通信 系统中最基本的构建块之一。 其用于提高功率放大器的效率。 通过减少功率放大器在其非线性区运行时产生的失真，功率放大器的效率可得到大幅提升。 不使用 CFR 或 DPD 算法的无线基站通常效率较低，因此运营和资金设备成本也较高。 一个输出 WCDMA 波形的典型 AB 类 LDMOS 功率放大器的效率约为 15－20％。 利用 CFR 和 DPD 算法，效率可提升至 40％，从而大幅降低网络 运营商 的资本支出和运营支出。 据 …
