a signal quality estimation circuit for generating a plurality of estimation results based on the signals transmitted from the at least one of the receiving devices, each of the estimation results corresponding to the receiving quality component of each receiving device for receiving the first packets broadcasted by the transmitter;
a control circuit, coupled to the signal quality estimation circuit, for determining whether each of the receiving devices is a target receiving device or not based on the receiving quality component of the corresponding receiving device and the signal quality threshold, wherein based on the control circuit determining that a number of ACK signals transmitted by at least one of the target devices within a unit period changes, the control circuit adjusts a consecutive transmission frequency transmission count to prompt adjustment of a signal quality component corresponding to a packet error ratio; and
a storage unit, coupled to the control circuit, for storing identification information of at least one of the target receiving devices;
wherein the transmitter is configured to broadcast the additional packets to the target receiving devices;
wherein the control circuit determines whether at least one of the target receiving devices needs to receive the broadcasted additional packets again according to the identification information and the receiving quality component of the at least one of the target receiving devices; and
wherein the transmitter rebroadcasts the additional packets again if needed.
