Wireless communication method and communication terminal device using the same

A wireless communication method of a communication terminal device, the wireless communication method comprising:

• sniffing, by the communication terminal device, a radio signal and capturing a packet from the radio signal;
• determining, by the communication terminal device, whether the packet meets a source condition or not, wherein the source condition comprises that the packet contains a specific transmitter address corresponding to a wireless transmitting device and a specific receiver address corresponding to a wireless receiving device;
• determining, by the communication terminal device, whether the packet meets a data condition or not if the packet meets the source condition, wherein the data condition comprises that the packet contains a specific packet type;
• extracting, by the communication terminal device, a data payload from the packet if the packet meets the data condition;
• determining, by the communication terminal device, whether a data error rate of the data payload is greater than a tolerable value or not;
• and
• sending, by the communication terminal device, an error correcting information to a server if the error rate of the data payload is greater than the tolerable value, such that the server provides an error correction parameter for updating a forward error correction coding scheme to the wireless transmitting device.
