Abstract:
1. A synchronization method in a Ultra Wideband (UWB) receiver, comprising: receiving a signal through a multipath channel; and synchronizing with a first multipath component of the received signal by computing a correlation value between the received signal and a template signal of the receiver in a predetermined search range, wherein the synchronizing with the first multipath component of the received signal includes, multiplying respective correlation values by corresponding channel coefficients in the predetermined search range and setting a largest value among values obtained by summing the multiplication results as a first multipath component to synchronize with the first multipath component of the received signal, or setting the largest value among values obtained by summing absolute values of respective correlation values in the predetermined search range as the first multipath component to synchronize with the first multipath component of the received signal, wherein the corresponding channel coefficients in the predetermined search range are obtained by iteratively performing the synchronization and by storing the corresponding channel coefficients in the predetermined search range at each synchronization.
