Abstract

A method for adjusting modulation ways in a wireless system is used in a system having a plurality of wireless work stations and an area network. Each wireless work station transmits signals to an area network by a network card. The wireless work stations modulated by one of pulse binary convolution coding (PBCC) and code compensation key shift modulation (CCK). The method comprises the steps of: identifying the receiving signals to determine the receiving signals to be modulated by pulse binary convolution coding (PBCC) or code compensation key shift modulation (CCK) by using the driving program so as to get an identified modulation way; and the medium layer instructing the wireless transmitting and receiving layer to receive signals by the identified modulation way.

Claims

1. A method for adjusting modulation ways in a wireless system for a system having a plurality of wireless work stations and a network card of an area network;

each wireless work station transmitting signals to an area network through the network card;

the network card including a driving program, a medium layer, and a wireless transmitting and receiving layer;

the wireless receiver being connected to the wireless receiving layer;

the wireless receiving layer being connected to a medium layer, and the medium layer being connected to the driving program;

the wireless work stations modulated by one of pulse binary convolution coding (PBCC) and code compensation key shift modulation;

the method comprising the steps of;

identifying the receiving signals to determine the receiving signals to be modulated by pulse binary convolution coding (PBCC) or code compensation key shift modulation (CCK) by using the driving program so as to get an identified modulation way; and

the medium layer instructing the wireless transmitting and receiving layer to receive signals modulated by the identified modulation way; and

changing the modulation way of the wireless work station into the identified modulation way.

2. A method for adjusting modulation ways in a wireless system for a wireless system;

the wireless system comprising

a plurality of first wireless work stations;

an area network;

each wireless work station transmitting signals to an area network by a wireless receiver in a network card of the area network;

the network card including a driving program, a medium layer, and a wireless transmitting and receiving layer;

the wireless receiver being connected to the wireless receiving layer;

the wireless receiving layer being connected to a medium layer, and the medium layer being connected to the driving program;

a second wireless work station;

wherein the first and second wireless work stations modulating signals by one of pulse binary convolution coding (PBCC) and code compensation key shift modulation;

wherein initially the first wireless work stations are communicated with the area network, but the second wireless work station is added to the communication afterward;

the method comprising the steps of;

identifying the receiving signals from the wireless work station to determine the receiving signals to be modulated by pulse binary convolution coding (PBCC) or code compensation key shift modulation (CCK) by using the driving program so as to get an identified modulation way;

the medium layer instructing the wireless transmitting and receiving layer to receive signals by the identified modulation way; and
