Optimizing the transmit energy in UWB multiple access communications in multipath fading channels
We propose a new transmit energy optimization method in UWB (ultra wideband) multiple access communications in multipath fading channels. We consider a packetized transmission mode, where each packet contains N/sub pre/ overhead symbols for synchronization purpose and N/sub B/ symbols for data transmission. The effect of packet update rate (N/sub R/), decimation factor (D), number of users (K/sub all/) and the length of PN-sequence (N/sub s/) on the transmitted energy are analyzed. Extensive numerical results are presented to show how these parameters can be chosen to obtain an optimum transmit energy for a given probability of acquisition.
