Abstract:
A method for improving the quality of the reception of data transmitted in a certain data channel of a received signal using a receiving device comprising a digital radio receiver to be tuned step by step to certain frequencies associated with said certain data channel, comprising the steps of:demodulating and decoding said certain data channel of the received signal, said certain data channel transmitting said data in a digital form, measuring the quality of said data in a digital form on one certain frequency and at least on one further certain frequency of said certain frequencies, choosing said one further certain frequency so that tuning the receiver thereto requires a tuning step, and producing a decision based on the results of the quality measurement on said digital data as to, whether said radio receiver will be kept tuned to the one certain frequency, whether it will be tuned to said one further certain frequency, or whether the quality will be further measured on another of said certain frequencies before the decision is made about returning the receiver.
