Two novel receivers for transmitted-reference ultrawide bandwidth wireless systems are proposed. The new receivers are derived by using iterative algorithms to implement the channel template estimators employed in previous receivers. While the new receiver structures are simple, simulation results confirm their superiority over previous receivers. The performances of the new receivers can be further improved by optimizing the energy allocation between reference symbols and data symbols within one data packet and by optimizing the number of samples used in correlation. Numerical examples show that the optimization can provide performance gains of up to 4 dB in some cases.
