نویسندگان
چکیده
Digital predistortion (DPD) is used to compensate for the distortion of power amplifiers (PAs). Inspired by physical structure PA circuit, a feedback in DPD model favored. In this letter, we proposed an infinite impulse response (IIR) modeling and linearization, modifying generalized memory polynomial (GMP) model. We also propose iterative identification algorithm estimate IIR-DPD coefficients. The experimental results shows that IIR-GMP can improve linearization performance compared with conventional methods.

Parallelizing Infinite Impulse Response Filters
In this paper, we present a parallel algorithm for edge detection based on Infinite Impulse Response filter (IIR filter).

متن کاملBehavioral modeling and linearization of a millimeter-wave power amplifier
The use of digital predistortion for linearizing a millimeter-wave power amplifier (PA) is investigated. A PA operating at 38 GHz is designed using an accurate non-quasi-static transistor model, taking into account both shortand long-term memory effects. A realistic test signal is then used for the identification of a nonlinear auto-regressive moving average (NARMA) behavioral model of the PA. ...

متن کاملInfinite-impulse and Finite-impulse Response Filters for Continuous-time Parameter Estimation
This paper examines two classes of algorithms that estimate a continuous time ARX type of models from discrete data: one is based on infinite impulse response (IIR) filters while the other is based on finite impulse response (FIR) filters. The IIR filters use continuous time state variable filters, and discretisation is performed on the filtered derivatives. In contrast, the FIR filters are in ...
متن کاملAn Infinite Impulse Response Equalizer for Magnetic Recording Channels
In this paper, we propose a method of designing an infinite impulse response (IIR) equalizer used to shape the readback signal to a partial response target in longitudinal and perpendicular recording channels. Based on the minimum mean-squared error (MMSE), the coefficients of the IIR equalizer are explicitly derived. For both recording channels, the proposed IIR equalizer performs better than ...
