Adaptive Threshold Control for a 1-bit ADC in a Low Complex IR-UWB Receiver

This letter proposes an adaptive threshold control algorithm for a low complex noncoherent IR-UWB receiver using a 1-bit ADC. To estimate and control a threshold level in the noncoherent IR-UWB receiver, it uses binary output of the 1-bit ADC instead of energy level of received signals using a high resolution ADC, which reduces hardware complexity of the receiver. Theoretical performance evaluation and computer simulation demonstrates that the performance of the proposed algorithm is similar to that of theoretically optimum one.
