A cyclic prefix is a copy of a portion of the end of an OFDM symbol which is put in front of each transmitted OFDM symbol: One immediate consequence of this approach is a reduction in data rates. However, it greatly reduces the ISI problem, as shown on the following figure: 2008-04-25 Cyclic Prefix: Motivation (2) 4 OFDM uses large symbol duration T s compared to the duration of the impulse response τ max of the channel to reduce the amount of ISI Q: Can we “eliminate” the multipath (ISI) problem?

Current implementation in public In telecommunications, the term cyclic prefix refers to the prefixing of a symbol, with a repetition The concept of a cyclic prefix is traditionally associated with OFDM systems, however the cyclic prefix is Download as PDF &middo PDF | We address the impact of a too short cyclic prefix on multicarrier systems such as Orthogonal Frequency Division Multiplex (OFDM) and Discrete | Find In this paper, we consider different types of guard intervals for OFDM systems, i.e.
