    Abstract: A method of generating a signal being phase-shifted at a predetermined phase- shift division factor relative to a reference signal is disclosed. The method comprises: using the predetermined phase-shift division factor for selecting a modulation amplitude, modulating a control signal at the selected modulation amplitude, and combining the reference signal and the control signal to form the phase- shifted.

    Abstract: A programmable compute unit with an internal register with a bit FIFO for executing Viterbi code is configured to accumulate in the forward path the best-path to each state in an internal register and store the survivor trace back information bit for each state in each stage in a bit FIFO; and in the trace back, selecting the optimal best-path through the Viterbi trellis by tracing through the bit trace back information survivor bits beginning with the survivor bit of the last stage path; and generating in response to the Viterbi constrain length and a current bit FIFO address, the next bit FIFO address and decoded output bit for the next previous stage.

    Abstract: An algorithm for correcting the output of an analog I/Q demodulator (10) without the need for calibration or storing state information. The output of the analog I/Q demodulator (10) is digitized, and the discrete-time samples are divided into segments. A digital frequency transform (e.g., a Discrete Fourier Transform) (35) is computed for each segment. The effects of the non-ideal 1/Q demodulator are removed by identifying a set of image frequency candidates for each digital frequency transform, and for each image frequency candidate, estimating a set of demodulator imbalance parameters to characterize the demodulator imbalance at that frequency and correcting the digital frequency transform at the image frequency candidate using the imbalance parameters in order to minimize the effects of the imbalance. Each digital frequency transform is corrected independently and consequently no persistent state information needs to be saved between transforms.
