  • Forward power control determination in spread spectrum communications systems
    Patent number: 6526031
    Abstract: A spread spectrum communications system where power control mitigates received signal fluctuations. An implementation is described for forward power control wherein received data is checked for errors. Where an error is detected energy levels of the power control bits and traffic bits are determined. The energy level of the power control bits is compared against a first predetermined threshold wherein if the energy level of the power control bits is less than the first predetermined threshold an increased in forward power is requested. Otherwise, the energy level of the traffic bits are compared against a second predetermined threshold wherein if the energy level of the traffic bits is less than the second predetermined threshold a decrease in forward power is requested. Otherwise an increase is requested.
