摘要 目前,超宽带(UWB)技术由于其特有的优点受到越来越多的关注,其中,针对于UWB系统的MAC协议的设计逐渐成为热点。与现有无线通信系统相比,UWB系统占有更宽的频带,具有更高的传输速率,发射功率谱密度非常低,因此,需要设计符合该系统特点,满足该系统节能、高吞吐量以及低时延等要求的MAC协议。文章通过对现有用于UWB通信系统的MAC协议的综合分析和比较,提出对UWB-MAC协议设计的要求。 Recently, the ultra-wide band （UWB）-based technique is focused on more deeply along with the design of MAC （media access control） for its advantages. Comparing with the conventional wireless communication system, the UWB system has its unique characteristics, higher speed rate, lower PSD （power spectrum density）, etc. It is therefore necessary to propose advanced MAC protocols for matching the requirements of the system. In this study, the performance of various types of MAC protocols based on UWB system is investigated. The physical structures for different MAC protocols are compared. Some special demands from UWB for MAC are analyzed. The advanced design for the MAC protocols in UWB is proposed. It may provide the implementation base for future MAC protocols.
