High level modeling of an ultra wide-band baseband transmitter in MATLAB

Wireless personal area network (WPAN) system with ranges of 4-10 m become popular in replacing wire system, technologies such as Bluetooth and ZigBee used for this purpose but due to its low data rate of 1 Mbps which is not enough for large file transfer and applications like video streaming there is a need of technology which address all these issues, Ultra Wideband is such a emerging wireless technology which support data rates up to 0.5 Gbps. UWB with its Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) infrastructure is an ultimate choice for the transmission of high speed data by dividing its wide frequency spectrum into sub 14-bands. The architecture of MB-OFDM transmitter baseband is presented in this paper and its modeling in MATLAB is discussed in detail. Modeling of UWB PHY transmitter baseband in MATLAB is helpful for designing its commercial product by optimizing various parameters.
