Benefits, variants and applications of cyclic delay diversity

چکیده
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 introduced and discussed. We show the application to several types of wireless systems, in particular terrestrial digital video broadcasting, cellular mobile radio communications systems and a wireless communications system using adaptive bit loading (ABL). Simulation results highlight the benefits of CDD for these kind of systems. Copyright © 2008 John Wiley & Sons, Ltd.

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...
متن کاملAspects of Delay Diversity in OFDM
We consider several aspects of delay diversity in coded OFDM. The cyclic properties of the FFT allow to do delay diversity in a cyclic manner without exceeding the guard interval. We investigate the impact of different cyclic delays in terms of achievable diversity level, information theory and BER performance. Furthermore, we propose an interleaving and user assignment strategy which allows mu...
متن کاملA Robust Frequency Offset Estimation Scheme for OFDM System with Cyclic Delay Diversity
Cyclic delay diversity (CDD) is a simple technique to intentionally increase frequency selectivity of channels for orthogonal frequency division multiplexing (OFDM).This paper proposes a residual carrier frequency offset (RFO) estimation scheme for OFDMbased broadcasting system using CDD. In order to improve the RFO estimation, this paper addresses a decision scheme of the amount of cyclic dela...
متن کاملCooperative Coding Using Cyclic Delay Diversity for OFDM Systems
This paper proposes cooperative coding using cyclic delay diversity (CDD) for OFDM systems. The cooperative diversity is combined with channel coding while CDD is applied to the cooperative transmission of the multiple relays to improve the beneficial effects of the cooperating relays. Analyses of frame error probability (FEP) and the average channel power of the proposed scheme are shown. Simu...
