摘要
提出的同步器包括无匹配滤波器的符号同步模块,基于改进Moose算法的载波频偏纠正模块以及基于符号自相关的包检测模块。在0.13μmCMOS工艺下,实现相同的数据吞吐率528Msample/s,面积和功耗仅为传统实现方法的24%和25%。
An efficient synchronizer for OFDM-based UWB system was proposed, which consists of the filter-free sym- bol synchronizer, frequency synchronizer with improved Moose algorithm and sign-based auto-correlator. According to the results of synthesis using SMIC, 0.13 μm CMOS process, the proposed design can achieve the throughput requirement with only 24% gate count and 25% power consumption of the conventional four-parallelism approach.
