Abstract
A radio signal in a radio communication system may be filtered to prepare an EDGE-signal. In this case, the signal-to-noise-ratios are calculated according to a first operation in addition to previously known methods for detecting a neighboring channel interference. In addition, other variously tuned filters are activated when a corresponding threshold is reached, where the thresholds are associated with correspondingly intense interferences from neighboring channel influences. A filtering method or filter module can be mounted in an existing station behind an existing receiving filter. In the first filtering operation, the previous filter effect is reduced to the smallest amount possible before new filtering is carried out to produce a desired signal. The EDGE signals can also be produced in a simple manner from GMSK signals.
