UWB Multiband OFDM PLCP Preamble creating in Matlab ?

Hello, I will start coding UWB Multiband OFDM channel modelling in Matlab. I am planning Ecma İnteranational High Rate Ultra Wideband PHY and MAC Standard then I studied theotical part much. Now ı have to show all things that ı learnt on Matlab. It is my master thesis. I completed OFDM part in Matlab through the one book. Now firstly I have to complete PLCP Preamble part after PLCP Header and of course PSDU part. PLCP is 30 symbol and has two part. one is 24 symblo and oter 6 symbol. How ı can follow any way or how I can start coding in Matlab ? Great thanks
