An additional means of reducing envelope distorsion is to predistort the signal envelope.
The distortion reduction unit generates, from a received signal including a first distortion and a second distortion, a distortion-reduced signal in which the second distortion is reduced and the first distortion is left intact.
The distortion amount is expressed by a distortion building coefficient and a distortion parameter.
Distortion adjusting means (6) adjusts either or both of the amplitude and phase of the distortion produced by the distortion compensation distortion producing means (2-4).
Distortion delaying means (5) delays the distortion prior to or after adjustment by the distortion adjusting means (6).
Furthermore, the distortion image creation means (23) distorts the reference image by the distortion amount.
The estimate of distortion comprises a first term representing source coding distortion, and a bias term representing an estimate of distortion that would be experienced due to loss over said channel.
Because a warp distorts space, it also must distort time.
The fingerprint technique is based on the principle of applying very slight local spatial distortion to the pixels in a video image, and the like, by means of selected warp patterns.
This compensation distortion is then added with the transmitter distortion to cancel the transmitter distortion from the modulated signal; to thereby linearize the output.
The distortion, determined by the rate of change of the angular deviation is calculated and compared to preset distortion values.
The pre-distortion information is sent to a pre-distorter at the second location, where the pre-distorter can reduce the non-linearity effect using the pre-distortion information.
The present invention relates to a predistorter (25), a method for predistorting and to an amplifier including a predistorter.
A value of distortion for the rendered video, based on the depth map distortion and on a particular relationship between the depth map distortion and values of distortion for the rendered video, is determined.
It’s not just distortion – it’s a distortion within a distortion within a distortion.
Disclosed is a distortion compensation circuit that efficiently compensates for distortion.
A distortion calculating unit (180) calculates the distortion of the digital modulated signal.
The predistortion applied by the predistorter may be fixed or adaptive.
Accordingly, there is minimal distortion, and low total harmonic distortion level is achieved.
The distortion replica is used to cancel the distortion from the first transistor.
The rate-distortion model incorporates an overall macroblock mode distortion D that is defined as the sum of DAC a distortion due to AC coefficients, and DDC a distortion due to DC coefficients.
Provided are a distortion compensation circuit and a distortion compensation method that are capable of limiting the signal level of a post-distortion-compensation signal and improving the distortion compensation effect.
A method determines distortion in a video by measuring a spatial distortion in coded frames, and by measuring a temporal distortion and spatial distortion in uncoded frames.
A rate-distortion optimized embedding (RDE) coder (Fig. 5) optimizes rate-distortion performance by coding information bits in the order of their R-D slope.
