On the acquisition time for serial and parallel code search in UWB impulse radio

UWB (ultra-wideband) is an emerging technology for short-range wireless communications, such as WPAN (wireless personal area networks). In the context of UWB (ultra-wideband) impulse radio, one of the crucial challenges remains the acquisition of synchronization in terms of time, precision and number of operations. In this paper, we present a study on the acquisition time, for different code acquisition strategies, when considering the channel model adopted by IEEE 802.15.3a. Finally, we propose a simplified implementation of the acquisition algorithm based upon a coarser time frame quantization.
