Abstract :
This work assumes that local oscillators in individual transceivers are not identical. A difference in the drift of oscillator gives rise to a difference in pulse repetition rate between transmitter and receiver. This drift will be estimated in the paper. The performance of a proposed automated gain control (AGC) circuit to stabilize the gain of a time tracking loop is also investigated. Thus this work is on estimating the received signal amplitude, the initial offset and frame frequency differences between a pair of UWB impulse transceiver and the results will be useful for applications such as time transfer and synchronization.
