Sammanfattning

For ultra-wideband (UWB) communication, Rake receivers using matched filter detection show the best performance but they are complex to realize due to the inherent channel estimation problem and combining problem. Transmitted reference schemes, on the other hand, allow for a less complex receiver structure that is able to combine the energy from different multipath components without channel estimation. These schemes, however, show a performance loss due to non-linear operations on noise terms (generation of noise-noise crossterms) when forming the decision variable. This paper describes a receiver structure for UWB communication capable of capturing the energy from different paths without the need for channel estimation. The proposed hybrid matched filter correlation receivers reduce the performance loss, due to the noise-times-noise term.
