Web1) Start Position Detection: For the received collided signal, we first detect the number of collided packets by adopting a preamble detection method [17], [18], and then calculate the accurate ... WebThe purpose of the preamble is to allow time for the receiver in each node to achieve lock of the receiver Digital Phase Lock Loop which is used to synchronise the receive data clock to the transmit data clock. At the point when the first bit of the preamble is received, each receiver may be in an arbitrary state (i.e. have an arbitrary phase for its local clock).
