This paper represents low power and high speed 128-point pipelined Fast Fourier Transform (FFT) and its inverse Fast Fourier Transform (IFFT) processor for OFDM. The Modified architecture also provides concept of ROM module and variable length support from 128~2048 point for FFT/IFFT for OFDM applications such as digital audio broadcasting (DAB), digital video broadcasting-terrestrial (DVB-T), ...

This paper presents a reusable intellectual property (IP) Coordinate Rotation Digital Computer (CORDIC)-based split-radix fast Fourier transform (FFT) core for orthogonal frequency division multiplexer (OFDM) systems, for example, Ultra Wide Band (UWB), Asymmetric Digital Subscriber Line (ADSL), Digital Audio Broadcasting (DAB), Digital Video Broadcasting – Terrestrial (DVB-T), Very High Bitrat...

Digital broadcast systems have increasingly been deployed for various services such as Digital Video Broadcasting (i.e. DVB-S, DVB-T, etc.) and Digital Audio Broadcasting (DAB). Classical digital broadcast systems were designed with fixed modulation guarantee reliable communication even with very hostile channel environment. DVB-T2 terrestrial television standard is becoming increasingly import...

Rapid FPGA Prototyping of a DAB Test Data Generator using Protocol Compiler Klaus Feske, Michael Scholz, Günther Döring, Mark Langer FhG IIS Erlangen Department EAS Dresden Zeunerstr. 38, D-01069 Dresden, Germany, e-mail: [email protected] 1 Motivation Conventionally, the controller design for structured data stream processing is not well supported by tools [SHM-96]. So, we are faced with a ...

The aim of this paper is twofold: This paper presents a summary of our recent efforts for the enhancement of a computer-assisted Digital Audio Broadcasting Receiver with several alterations such as a personalization, service scanning, integration of podcasting into broadcasting, and a speech-based interfaces with an information retrieval system. The prototype is based on the mandatory features ...

Viterbi Decoders (VDs) are today widely used as forward error correction (FEC) devices in many digital communications and multimedia products, including mobile (cellular) phones, video and audio broadcasting receivers, and modems. VDs are implementations of the Viterbi Algorithm (VA) used for decoding convolutional or trellis codes. The continuing success of convolutional and trellis codes for ...

MP3 is the popular audio coding standard. But now, a new higher quality audio coding standard Advanced Audio Coding (AAC) is proposed and widely used. The quantization/re-quantization is essential in both MP3 and AAC. It proposes a new high accuracy estimation algorithm for MP3 and MEPG-4 AAC audio coding. The algorithm can be applied not only for re-quantization process in decoder, but also fo...

In order to enhance efficiency in designing Digital Audio Broadcasting (DAB) transport network applications we combine Protocol Compiler-based high level design methods with the Atmel System Designer SoC development suite. We define DAB requirements and outline design as well as validation of a Ensemble Transport Interface Monitoring Unit (EMU). Experimental results and conclusions concerning t...

Today, mobile phone or other handheld device owners expect also receiving and watching a TV stream besides the classical voice or text services. The Digital Video Broadcasting – Satellite services to Handheld (DVB-SH) is designed to transport mobile TV services. It also supports a wide range of mobile multimedia services, e.g. audio and data broadcast as well as file download services [1], [2].
