Evaluation of Diversity Gain in Digital Audio Broadcasting
نویسندگان
چکیده
Digital Audio Broadcasting (DAB) is a digital method of delivering radio services from base station to the receiver. The main aim of this paper is to get better reliability of DAB reception in mobile (moving) environment. DAB is very forceful in mobile environment, but in some situations, reception fails in certain spots due to undesired audio interruptions. Antenna diversity systems are considered to improve the diversity reception in DAB. The diversity gain depends on the two characters a) correlation of the signals from the different antennas which is influenced by antenna separation, b) parameters of transmitted signals. In this paper, theoretical evaluations of DAB are to be considered. Different parameters of DAB transmitted

متن کاملCyclic Delay Diversity: Effective Channel Properties and Applications
We briefly explain the concept of cyclic delay diversity (CDD) as a variant of standard conformable delay diversity techniques. Usually being implemented at the transmitter side of an OFDM based system, the application of CDD is recognized at the receiver side only by observing modified channel propagation conditions. Therefore, we analyze the effect of CDD on the channel fading properties obse...
