| Abstract: | Firstly,a transceiver of UWB systems with multiple antennas is proposed by employing the special space-time diversity structure,where the corresponding detection algorithm is also presented.Then,by exploiting the first-order cyclostationarity in the received signals incurred by the pulse-position modulation format,a low complexity blind channel estimation method without estimation ambiguity is proposed for the UWB system with space-time diversity.Simulations demonstrate that the proposed blind channel estim... |
