The number of OFDM symbols within one subframe is either 14 for normal cyclic prefix, or 12 for extended cyclic prefix. Create the cell-wide settings structure. You can use MATLAB and Simulink to: Design, test, and perform link-level simulation on OFDM waveforms; Customize OFDM parameters such as training signal, zero padding, and cyclic prefix with functions and blocks; Apply OFDM into your wireless system design to analyze metrics such as link performance, robustness, channel estimation, and equalization How to replace cyclic prefix by NPR filter in Learn more about ofdm, replace cp by filter, ber performance HDL simulink: DVB-T OFDM pilot insertion/cyclic Learn more about simulink coder, hdl, ofdm, dvb, dvb-t HDL Coder This MATLAB function performs DC subcarrier insertion, inverse fast Fourier transform (IFFT) calculation, cyclic prefix insertion, and optional raised cosine windowing and overlapping of adjacent OFDM symbols of the complex symbols in the resource array, grid.

LTE Timing Sync : Cyclic Prefix Correlation This is about finding the symbol boundary (the start of a OFDMA symbol) by using the fact that Cyclic Prefix is an exact copy of the last part of OFDM symbol. Adding cyclic prefix in ofdm - QAM16.
