Abstract
High reliable wireless communication with big data rate in high-speed moving scenarios is currently a hot topic, and channel sounding plays an very important role in the related research as a basic tool to know the channel characteristics. For MIMO channel sounding in high-speed moving scenarios, to meet the requirement of CIR measurement speed is a big challenge so that the fully parallel MIMO structure has to be used, which will induce severe crosstalk at the receiver and usually, the problem can be solved by CDM and FDM methods. But until now, which solution is better, there is no conclusion. So, in this paper we aim at developing a channel sounder that can support 44 MIMO sounding at the speed of above 1000 km/h after the performance comparison of FDM and CDM. Based on the autocorrelation and orthogonal properties analysis of common used signal for CDM, including m, ZC and LS sequence, we choose the FDM solution utilizing the multi-carrier technique, because of its higher measurement dynamic range. And finally, we complete the implementation and validation of the hardware.
