  • Publication number: 20070030065
    Abstract: A transmitter includes generating unit configured to generate a feedback signal and an analyzing unit configured to analyze transmission quality in a time domain and in a frequency domain by using the feedback signal. The transmitter also includes an adapting unit configured to adapt the pre-distorter if the transmission quality is below the threshold.

  • Patent number: 7123889
    Abstract: A radio transmitter, comprising: a feedback loop (314) which feedback loop comprises a variable attenuator and a signal analyser, means (300, 302, 304, 306, 308, 310, 312) for transmitting a signal on a predetermined radio channel, means (308) for changing attenuation level and for attenuating the feedback signal, means (316) for defining power levels on the radio channel and on the adjacent channels, means (312) for analysing the power levels to generate first and second results of analysis and for comparing the first and second results of analysis, means (318) for delaying a transmitted signal to derive a reference signal, means (312) for comparing the feedback signal and the reference signal to generate an error vector and means (320) for generating a test alarm.
