Memory Amplifier Simulation Program (Memory Saleh Model)

The Memory Amplifier Simulation Program (Memory Saleh) serves as a nonlinear distortion model for pre-memory power amplifiers in predistortion equalization projects. This program simulates signal transmission and distortion through amplifiers using mathematical representations of memory effects, typically implemented through difference equations or state-space models that capture both amplitude-to-amplitude modulation (AM/AM) and amplitude-to-phase modulation (AM/PM) conversions with hysteresis. By modeling these nonlinear characteristics, engineers can better understand and control signal output quality. The simulation typically involves computational methods for solving nonlinear differential equations and may include algorithms for parameter extraction from measured data. Implementation often utilizes MATLAB or Python with numerical integration techniques. This program significantly enhances predistortion equalization performance by providing accurate distortion modeling, thereby improving overall signal quality. Furthermore, it finds extensive applications across various fields including wireless communications, optical fiber communications, radar systems, and acoustics engineering. In these domains, the Memory Amplifier Simulation Program serves as a vital tool, offering engineers an advanced platform for research and development of high-frequency amplifier systems with memory effects compensation.
