基于FPGA的DS-UWB多用户检测的实现

Implementation of Multiuser Detection for DS-UWB Based on FPGA

在自适应最小均方误差的DS-UWB多用户检测方案的基础上,重点研究了多用户检测在FPGA上的实现性能。在FPGA的实现过程中选择了LMS算法来调整权系数,提出了一种利用SOPC开发的方法将接收数据烧写入Flash中的存储方式。另外,为了协调Flash与FPGA时钟频率不同的问题,提出了一种使用FIFO的接口方式来提高设计的灵活性和实现性能。

The implementation of MUD of DS - UWB on FPGA is presented in this paper. The scheme of MUD in DS - UWB is based on the adaptive MMSE criterion. LMS algorithm is adopted in the FPGA implementation design. A storage scheme which can program the received data into hash by the SOPC design is proposed. In addition, an interface scheme using FIFO is demonstrated which can provide better performance and flexibility for the design.
