Problems solved by technology

If the transmitted radio signal is of poor quality, data / voice signal receivers may have difficulty understanding the signal content
Also, the poor quality of the transmitted radio signal may result in the need to retransmit the data
This retransmission of data is time-consuming and bandwidth-intensive

Embodiment Construction

[0051] FIG. 1 schematically shows the structure of a mobile radio network 100 . The mobile radio network 100 provides radio communication to users of mobile stations via a radio interface 105 via a radio base station 110 . A mobile station 115 capable of communicating within a mobile radio network 100 is shown in FIG. 1 . The radio base station 110 is connected to a radio network controller 120 which in turn is connected to a core network 125 . The mobile radio network 100 typically comprises a plurality of radio network controllers 120 each connected to a plurality of radio base stations 110 . The mobile radio network 100 may be based on any standard for mobile radiotelephony, such as Wideband Code Division Multiple Access (WCDMA), Global System for Mobile Communications (GSM), or D-AMPS (such as those specified in EIA / TIA-IS-54 and IS-136). of)) run.

[0052] In various embodiments of the mobile radio network 100 , the mobile radio network 100 provides voice services as w...

Abstract

By the present invention is provided an inventive radio transmitter and a method to operate a radio transmitter, by which the quality of a transmitted radio signal can be improved. The radio transmitter comprises at least one digital filter having adjustable parameters. Via a control signal input the transmitter can receive a feedback signal being indicative of the output signal from the transmitter. The radio transmitter comprises programmable digital circuitry adapted to analyzing the feedback signal and to generating an analysis result. The programmable digital circuitry is further adapted to adjusting the adjustable parameters of the digital filter in accordance with the analysis result.

Description

technical field [0001] The present invention relates generally to the field of radio communications, and in particular to radio transmitters. Background technique [0002] Mobile radio communications have become increasingly popular over the past decade, and many mobile radio networks provide data communication services as well as voice services. In voice and data communication services, the quality of radio transmission is paramount. If the quality of the transmitted radio signal is poor, the receiver of the data / voice signal may have difficulty understanding the content of the signal. Furthermore, the poor quality of the transmitted radio signal may result in the need to retransmit the data. The retransmission of such data is time-consuming and bandwidth-consuming. Contents of the invention [0003] The problem addressed by the invention is that of how to improve the quality of radio signals emitted by radio transmitters. [0004] This problem is solved by a radio tr...
