Consider the cyclic prefix in an OFDM system. a) Assume that \( \mathrm{x} \) is a row vector of length 256 which represents an (macro) OFDM symbol (without cyclic prefix). The Matlab command \( [\mathrm{x}( \) end \( -63 \) : end \( ), \mathrm{x}] \) will create a cyclic prefix for \( \mathrm{x} \). This cyclic prefix has the length of b) The cyclic prefix must be discarded
