— In ultra-wideband (UWB) indoor dense multi-path transmission environments, traditional coherent Rake receiver requires estimation of channel parameters. Moreover, in order to collect enough signal energy from dense multi-path components, the number of Rake fingers must be large enough. Consequently, the receiver structure is too complex to be implemented in practice.
