database on a computer and a solid state device the processor and the memory may be combined into a single element which may be implemented in hardware software or firmware referring now to network element 404 the operation of the constituents is described the receiver 408 is capable of receiving signals from network element 402 via the communications link 406 the receiver 408 and or the processor 409 is capable of determining the quality of the link 406 method step 302 the processor 409 is also capable of determining the required group and element within the group from the quality determination by interacting with the memory 410 method steps 303 304 the memory 410 contains a look up table a formula or other means which enables the processor to link the quality determination to the appropriate identification numbers or symbols which should be sent to network element 402 in order that the optimum transmission parameter is selected the transmitter 411 is capable of sending signals to network element 402 via the link 406 and the transmitter sends details of the selected group and element method steps 305 306 there are many techniques well known in the art for determining the quality of a communications link quality decisions can be based on parameters including but not limited to mean interference level snir error rate channel dispersion and fading.
