Performance Comparation of TR and FDE in the MB - IR - UWB System Based on MIMO
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 the authors 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.
