FORWARD POWER CONTROL DETERMINATION IN SPREAD SPECTRUM COMMUNICATIONS SYSTEMS

摘要

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 is compared against a first predetermined threshold (105) wherein if the energy level of the power control bits is less than the predetermined threshold an increase in forward power is requested (106). Otherwise, the energy level of the traffic bits are compared against a second predetermined threshold (107) wherein if the level of the traffic bits is less than the second predetermined threshold a decrease in forwards power is requested. Otherwise an increase is requested (108).
