DIGITAL RADIO -- The Eureka 147 DAB System
Flexibility and choice -The DAB signal is essentially a highly flexible over-air 'data-pipe' that can broadcast a wide range of service types, from purely audio-based to multimedia. Typically, each multiplex can broadcast five or more high-quality audio services plus a number of extra services. The multiplex can be dynamically reconfigured to introduce additional services, temporary or permanen...
متن کاملReceiver Synchronization for Dab with Transmission Mode Iii
Synchronization is the key part of OFDM receiver. A method to estimate Time Synchronization in DAB receiver is based on analysis of phase reference symbol is given. Synchronization analysis is performed under Rician channel with SNR 20dB and -8dB. Keyword: Fine time synchronization, phase reference symbol, OFDM and DAB.
متن کاملBroadcast Transmission to Prioritizing Receivers
We consider a broadcast model involving multiple transmitters and receivers. Transmission is performed in rounds, where in each round any transmitter is allowed to broadcast a single message, and each receiver can receive only a single broadcast message, determined by a priority permutation over the transmitters. The message received by receiver R in a given transmission round is the one sent b...
متن کاملEnergy-Efficient User Association in Broadcast Transmission
This paper addresses the user association problem in a multi-cell broadcast transmission. We seek minimal total energy consumption by considering both transmission power and operational power cost. We propose a novel distributed solution based on network utility games and using so-called Markovian approximation we design the distributed base station (BS) selection algorithm. Extensive simulatio...
متن کاملDetection of digital transmission systems for voice quality measurements
In-service, Non-intrusive Measurement Devices (INMD) estimate the perceived quality of the telephone link by extracting quality-defining criteria like echo attenuation, echo delay, active speech level, noise level, frame losses and transient failures from a telephone call. In addition, the quality depends on the used digital transmission systems (codec systems). This paper proposes a method to ...
