Digital Radio Mondiale ( DRM ) DIGITAL RADIO MONDIALE DRM LOCAL COVERAGE USING THE 26 MHz BROADCASTING BAND
ثبت نشده
چکیده
This document reports on a carefully designed set of fixed and mobile reception tests in Mexico City on the DRM (Digital Radio Mondiale) system at a frequency in the uppermost shortwave broadcasting band – around 26 MHz – for local broadcasting. The testing was done during July 2005. These were not operational tests; that is, neither the transmitter antenna, nor antenna location, nor transmitter power were designed for real broadcast operations. However, from the test results, as documented throughout the report, the characteristic of an operational broadcasting station to cover a densely populated city as Mexico DF can be determined.

متن کاملTransmission Rate Enhancement Schemes for Digital Radio Mondiale Systems
In this paper, transmission rate enhancement schemes for DRM (Digital Radio Mondiale), which is a worldwide standard for digital AM and FM broadcasting in the AM and FM bands below 170 MHz, are presented and compared. The data rate of the legacy DRM system is supported up-to 186kbps with 16QAM and MLC (Multi-level Coding) at 100 kHz bandwidth. However, this rate is not sufficient to achieve new...

ISDB-T International standard is currently adopted by most Latin America countries and is already installed in most TV sets sold in recent years in the region. To support interactive applications in Digital TV receivers, ISDBT defines the middleware Ginga and its declarative language NCL (Nested Context Language). Similar to Digital TV, Digital Radio standards also provide the means to carry in...
متن کاملRobust Sampling Frequency Offset Estimation for OFDM over Frequency Selective Fading Channels
Digital radio mondiale (DRM) is a terrestrial radio broadcasting standard to replace existing analogue AM and FM broadcasting, which is based on an orthogonal frequency division multiplexing (OFDM) technique. This paper focuses on the issue of estimating a sampling frequency offset (SFO) in OFDM-based broadcasting systems under frequency selective fading channels. In order to design a robust SF...
متن کاملLow-Power and Optimized VLSI Implementation of Compact Recursive Discrete Fourier Transform (RDFT) Processor for the Computations of DFT and Inverse Modified Cosine Transform (IMDCT) in a Digital Radio Mondiale (DRM) and DRM+ Receiver
This paper presents a compact structure of recursive discrete Fourier transform (RDFT) with prime factor (PF) and common factor (CF) algorithms to calculate variable-length DFT coefficients. Low-power optimizations in VLSI implementation are applied to the proposed RDFT design. In the algorithm, for 256-point DFT computation, the results show that the proposed method greatly reduces the number ...
