Patent ID: 7444132

Claim:
In a radio communication system having a first communication station that at least receives send signals sent thereto by at least a first send station upon a channel susceptible to non-ideal communication conditions, an improvement of apparatus for causing a filter element forming part of the first communication station to exhibit selected filter characteristics, said apparatus comprising: a parameter adjuster adapted to receive indications of the communication conditions of the channel upon which the send signals are sent, said parameter adjuster for selecting a value of a parameter defining a filter characteristic of the filter element, the value selected by said parameter adjuster used to filter the send signal at the filter element within a selected response time and at a selected quality level, the value of the parameter selected by said parameter adjuster applied to the filter element to cause the filter element to exhibit the selected filter characteristics, wherein a signal to noise ratio is associated with the send signals received at the first communication station and said parameter adjuster receives indications of the send signal comprising send signal amplitude related values, wherein the send signal amplitude related values that said parameter adjuster receives comprise signal to noise ratio values, the value selected by said parameter adjuster responsive to the signal to noise ratio values of the send signal.
