论文摘要
本文集中于构建具有单发射器和多个接收器的基于多ANTENNA FPGA的通道声音，以实现室内环境的无线传播特征。 DSSS信号（具有实际最大长度PN序列的扩散）是传输的，该信号与每个接收器处相同的PN序列相关，以获得功率延迟曲线。将多重延迟配置文件平均，然后将结果发送到主机。为了利用较高的带宽，与PN序列的生成和并行相关相关的计算昂贵任务移至每个USRP中存在的FPGA（通用软件无线电外围设备）中。使用Vivado HLS构建了通道声音块，并与RFNOC（芯片上的RF网络）框架集成，然后在USRP X310设备上使用。
This paper concentrates on building a multi-antenna FPGA based Channel Sounder with single transmitter and multiple receivers to realize wireless propagation characteristics of an indoor environment. A DSSS signal (spread with a real maximum length PN sequence) is transmitted, which is correlated with the same PN sequence at each receiver to obtain the power delay profile . Multiple power delay profiles are averaged and the result is then sent to host. To utilize high bandwidth, the computationally expensive tasks related to generation and parallel correlation of PN sequences are moved to the FPGA present in each USRP (Universal Software Radio Peripheral). Channel sounder blocks were built using Vivado HLS and integrated with RFNoC (RF Network on Chip) framework, which were then used on USRP X310 devices.
