An Efficient Hierarchical Modulation based Orthogonal Frequency Division Multiplexing Transmission Scheme for Digital Video Broadcasting
Due to the increase of users the efficient usage of spectrum plays an important role in digital terrestrial television networks. In digital video broadcasting, local and global content are transmitted by single frequency network and multifrequency network respectively. Multifrequency network support transmission of global content and it consumes large spectrum. Similarly local content are well ...
متن کاملBenefits, variants and applications of cyclic delay diversity
Cyclic delay diversity (CDD) is a simple multiple antenna technology which provides additional diversity in Rayleigh fading channels, and therefore, improves the system performance. We recall the principles of CDD and discuss the properties and impact of this transmit (TX) antenna diversity technology. Different applications motivate variations of the CDD principle. This variants are briefly in...
متن کاملPerformance of Cyclic Delay Diversity in Ricean Channels
Cyclic delay diversity (CDD) provides additional diversity in Rayleigh fading channels, and therefore, improves system performance. For line-of-sight (LOS) propagation, e.g. the additive white Gaussian noise channel, the implementation of CDD yields to a performance loss. Therefore, we investigate CDD for Ricean channels with different Ricean factors. To combat the SNR loss for significant LOS ...
متن کاملSynchronization for a DVB-T Receiver in Presence of Strong Interference
We consider synchronization of a multi-antenna receiver for terrestrial digital video broadcasting (DVBT) in the presence of strong co-channel interference. Thereby, we use a detection approach to find the symbol starts from the received orthogonal frequency division multiplexed (OFDM) signals. We propose two algorithms that exploit different features of the DVB-T signal. Both algorithms take a...
متن کاملSynchronization for a DVB-T receiver in presence of cochannel interference
This work was funded by IST project ANTIUM. Abstract This paper deals with the synchronization of a multi-antenna receiver for terrestrial digital video broadcasting (DVB-T) in the presence of strong co-channel interference. Two algorithms are proposed which exploit different features of the DVB-T signal. Both algorithms take advantage from the spatial diversity provided by the antenna array. T...
