摘要：
For the chip rate sampled channel impulse response of the IR-UWB system, a novel optimum data-aided channel estimation scheme is proposed that utilizes multi-templates to extract the frame-level samples from the received signal. Each frame-level rate sample for any given template is decomposed to a sum of a composite channel parameter (i.e., a linear combination of some channel parameters) and a noise. Based on these frame-level rate data and the maximum likelihood (ML) criterion, the ML estimates can be obtained for the composite channel parameters contained in these samples. The channel parameters can be computed through solving a set of the linear equations determined by the composite channel parameters. The simulations are provided to demonstrate the effectiveness of the proposed approach.
