OFDM Synchronization Improved Algorithm Based on Cyclic Prefix . T.Y. Zhang, G.F. Chen, X.C. Zhang . School of Electronic & Information Engineering . Changchun University of Science and Technology . Changchun, China . Abstract — The current study synchronization algorithm based on cyclic prefix, requirements of cyclic prefix length cannot be

a) I. I. … Cyclic prefix and pilot synchronization improves the OFDM system in terms of BER of the system which also depends on the length of the cyclic prefix .Till a certain value of Cyclic Prefix(20 percent), BER value decreases which further remains constant (.0001). Higher value of BER is achieved at the cost of The cyclic prefix is created so that each OFDM symbol is preceded by a copy of the end part of that same symbol. Different OFDM cyclic prefix lengths are available in various systems. For example within LTE a normal length and an extended length are available and after Release 8 a third extended length is also included, although not normally used.

For the normal mode, the first symbol has a cyclic prefix of The concept of a cyclic prefix is traditionally associated with OFDM systems, however the cyclic prefix is now also used in single carrier systems to improve the robustness to multipath propagation. Principle. A cyclic prefix is often used [citation needed] in conjunction with modulation to retain sinusoids' properties in multipath channels. So it can be seen from the graph that in an OFDM without Cyclic Prefix over AWGN i.e. fig.

In MIMO-OFDM cyclic prefix is used to remove inter symbol interference. The cyclic prefix is nothing but tail symbols of massage frame and it prepended to that massage frame.

Modeling of the mathematical equation of the Orthogonal Frequency Division Multiplexing, Inverse fast of the cyclic prefix length and the channel spread. 7.

The cyclic prefix length will be determined later for the purpose of removing the ISI of the precoded OFDM … Cyclic Prefix (CP) length on the downlink Capacity in a base-band synchronized SISO-OFDM context. To measure this impact, the capacity, measured in bits per second per hertz, is chosen as quality parameter. The study shows how the lengthening of the CP affects Spectral Efficiency Loss (SEL) and Signal to Interference and Noise Ratio (SINR). OFDM receiver under two-path fading channel.

In Section II, the OFDM system model is introduced. The CP-based blind symbol synchronization algorithm is presented in Section III, 2007-11-13 The cyclic prefix is a data duplicate in the OFDM symbol before transmitting to minimize inter symbol interference and inter channel interference [5].

January 2008, version 1.0 Cyclic Prefix-ed OFDM. A cyclic-prefixed OFDM (CP-OFDM) transceiver architecture is typically implemented using inverse discrete Fourier transform (IDFT) and discrete Fourier transform (DFT) blocks (refer Figure 13.3).
