This method may not be very accurate depending on situation. So we would not use this method only to find the start of a symbol, but this can be a good rough estimate and very simple to implement. Following is a sample Matlab code to calcualting correction with the length of cyclic prefix sliding along the I/Q data … A cyclic prefix is then appended to each OFDM symbol, which allows for computation of circular convolution through linear convolution if the cyclic prefix is … 2008-02-17 Adding cyclic prefix in clipped ofdm.
