Abstract: The invention relates to a method for controlling the operating point of a transistor of a power amplifier for amplifying time division multiplex (access) TDM(A)-signals. Methods to compensate drifts of the operating point caused by temperature variations are in principle known in the art. However, the methods known in the art have the disadvantage that they are not precise enough during the operation of such power amplifiers, in particular when amplifying high-frequency TDM(A)-signals. In order to overcome said problem the invention proposes to carry out the controlling of the operating point during null power time slots of said TDM-signal.

Abstract: The invention relates to a method of preparing signals (X and Y) to be compared to establish predistortion at the input of an amplifier (12), the signals comprising a signal (X) before amplification and a signal (Y) after amplification by said amplifier. Preparation includes time aligning (22) the signal before amplification (X) with the signal after amplification (Y) before using them to establish said predistortion. The invention preferably operates in two stages, namely a stage of coarse time alignment, in which the signal before amplification (X) is subjected to a time delay comprising an integer number of first time units, and a stage of fine time alignment, in which a delay or advance value of a fraction of the first time unit is determined.

Abstract: To enable subscribers to comfortably receive service, telecommunications carrier to increase the number of subscribers, and to allow base stations to reduce the processing burden. The effective Rate measuring portion measures the average effective Rate of the subscriber at the monitoring period Tn and the comparison portion monitors these results. The channel switching control portion carries out channel switching based on the report from the comparison portion if the average effective Rate falls below the threshold value Sdc or rises above the threshold value Scd. Since the value of the threshold value Scd can be decreased in proportion to the frequency of switching from CCH to DCH, the extent to which the subscriber can use the DCH is increased.
