摘要：
The Multi Band-Orthogonal Frequency Division Multiplexing Ultra Wide Band (MB - OFDM UWB) system is a low power (- 41.3 dBm / MHz); short-range (less than 20 m); high speed (53.3 - 480 Mbps) wireless technology with band width (3.1 to 10.6) GHz. The UWB spectrum is divided into 14 sub bands, each with 528 MHz bandwidth. Each OFDM symbol is transmitted / received a cross each sub band. In this paper, a hybrid digital modulation technique is proposed to increase the data rate in IEEE 802.15.3a MB-OFDM UWB standard. The hybrid digital modulation, QPSK & 16-QAM, is proved to double the data rate as compared with IEEE 802.15.3a QPSK modulation within acceptable limit of Bit Error Rate (BER).
