摘要：In order to improve the channel capacity of the multiband impulse radio ultra-wide- band (MB-IR-UWB) system, the multiple input and multiple output (MIMO) technology is introduced to MB-IR-UWB system, and we get a new MB-IR-UWB system based on MIMO. But the introduction of MIMO technology brings multi-stream interference (MSI) and same frequency interference (SFI). Meanwhile, there may be inter-symbol interference (ISI) over the multipath channel proposed by IEEE 802.15.3a. To eliminate these interferences, it is necessary to add an equalization technique which is a technique used for increasing the energy of the desired signal and reducing the energy of the undesired signal. In this system, we introduce time reversal (TR) equalization and frequency domain equalization (FDE) to the new system and compare the performance of the two equalizations. In this paper, by MATLAB simulation, we compare the robustness to channel and the anti-interference performance of two different equalizations in the MB-IR- UWB system based on MIMO.
