摘要： A method of generating values of a predistortion look up table for linearization of a transmitter. The method includes accumulating a plurality of pairs of values representing input and output values of samples entering one or more non-linear elements of the transmitter, fitting the pairs of values into a parameteric model of at least one of the one or more non-linear elements, so as to determine values for the parameters of the parameteric model, and generating values of the look up table responsive to the fitted parameteric model.

摘要： A transmitter has a transmission path with an IQ modulator and a feedback path with an IQ demodulator. DC offset is determined by estimating a DC offset of the IQ demodulator, adaptively estimating a DC offset of the IQ modulator at least partially from the demodulator DC offset, subtracting the estimated demodulator DC offset from the feedback path and subtracting the estimated modulator DC offset from the transmission path.

摘要： A method of assigning values to parameters for IQ mismatch cancellation. The method includes providing values to a processing path of a communication device, passing the provided values through an IQ modulator, at least one non-linear element and an IQ demodulator, to produce distorted values, and estimating at least one parameter for cancellation of IQ mismatch effects of the communication device responsive to the provided values and to the distorted values.

摘要： In an embodiment, a transmitter section for a mobile device includes a predistorter for predistorting an input signal input to a modulation section. Predistortion values may be selected from a look-up table in response to a fed back signal from the output of the modulation section. A delay between the input signal and the fed back signal may be determined in two stages: a coarse delay estimation for determining a whole number of sample cycles, and a fine delay estimation for determining a fraction of a sample cycle to be added to the coarse delay estimation value.

摘要： Linear transformations are carried out on a matrix that represents information such as an image or a communication. In an aspect, the matrix is processed to remove duplicate information. The duplicate information can be duplicate rows, or zero rows. This matrix is then transformed into a modifed matrix, indicating duplicate information is removed to produce a modified matrix.
