How the frequency hopping block works in MB OFDM UWB?

[cambyzhu]

Currently I am trying to simulate a very basic MB OFDM UWB system which base on the Matlab center "Fix point UWB OFDM system". But I do not understand how the system change it's fc to each sub-band. Can anybody tell me why and how the frquency hopping block works and explain what are the basic block I can left if I just want to simplify the system?
The system is on this website
