This paper presents a method to estimate time and direction of arrival (TOA and DOA) of impulse radio ultra wideband (IR-UWB) system based on matrix pencil (MP) in a multipath communication channel. It is used to recover time and angle from the channel frequency response. This algorithm only requires a single channel estimate and can estimate TOA and DOA easier and faster. The results show that TOA...
In order to enhance the transmission performance of the IR-UWB (impulse radio ultra wideband) system, the space-time technology of MIMO (multiple input and multiple output) has been considered. In view of the low power in the UWB mobile terminal, we need to estimate the channel in the receiver when using the space-time code. However, the complexity of the terminal is increased. For this reason, the...
This paper presents a method to estimate Time of arrival (TOA) of impulse radio ultra wideband (IR-UWB) in a multipath communication channel. Matrix Pencil (MP) is used to recover these delays from the channel frequency response. This algorithm has some key advantages over traditional super-resolution techniques such as multiple signal classification (MUSIC) method. Most importantly, Matrix Pencil...
The Propagator Method (PM) is extended to application in super-resolution time-of-arrival (TOA) estimation for ultra wideband (UWB) system, which need not any eigen- decomposition calculation and reduce the computation load in practical UWB implementation. Then TOA estimation is investigated in the presence of correlated complex fading amplitudes for UWB rays. In the UWB channel models proposed so...
