Symbol error based power control for mobile telecommunication system |
摘要 |
A mobile telecommunication system power control loop includes a symbol error rate detector to detect a number of symbol errors induced during transmission, a summing node to subtract the output of the symbol error rate detector from a symbol error rate target, a multiplier to introduce an adjustment factor, and an integration element to sum the output of the multiplier with past outputs of the multiplier. The output of the integration element is a signal power to noise power ratio target which is used to control the transmission power of the mobile telecommunication system. In one embodiment the symbol error rate target is a constant or parameter set by the user. In another embodiment the symbol error rate target is adjusted automatically to maintain a constant frame error rate.
