1. A portable monitoring device comprising a housing, a physiological parameter acquisition circuit, a signal transmitting circuit, and a signal receiving circuit;
wherein the physiological parameter acquisition circuit is configured to acquire a physiological parameter of a monitored object;
the signal transmitting circuit is configured to transmit the physiological parameter to a wireless access point through a communication signal which carries the physiological parameter and is generated by the signal transmitting circuit; wherein a current transmission power of the communication signal is determined by the signal transmitting circuit according to a current communication state of the portable monitoring device;
the signal receiving circuit is configured to receive the communication signal which is transmitted by the wireless access point, to filter the communication signal, and to extract communication data from the communication signal; wherein the filtering filters an interference signal of another communication channel, which is other than the communication channel, which is used by the signal receiving circuit.
