Low complexity TOA estimator for multiuser DS-UWB system

With the assumption that TOA is the integer multiples of chip duration, our decoupled multiuser ranging (DEMR) estimator employs integrate-and-dump filter (IDF) in chip sampling

In the optimal case, the symbol-level precoded transmit signal is obtained as the solution to an optimization problem tailored for a given set of users’ data symbols..

It is shown that the modified TR scheme outperforms simple TR and TR with circular shift scheme specially at higher number of simultaneous users.. For instance for 15

Based on an optimal analytical allocation solution, we proposed a simplified cross-layer approach which combines the user QoS requirements (priority level) and the user

Simulation results showed that the multiuser cross-layer solution outperforms the single-user WiMedia solution and that the soft-QoS users satisfaction in the

Thanks to a given noise level δ and a well-suitable inte- gration length window, we show that the derivative estimator error can be O (δ n+1+q q+1 ) where q is the order of
