  • A novel multi-rate MB-OFDM ultra-wide band (UWB) system is proposed, in which users are distinguished from their unique time-frequency codes (TFC). Also an adaptive TFC allocation algorithm is given to minimize total transmitting power with the constraint of the minimal data rate requirement of each accessed user. Theoretical analysis and experimental results show that the proposed system and allocation algorithm are able to increase system access capacity of multi-rate users and save power effectively, which is just an UWB system needed.
