Improved Rayleigh Fading Channel Simulation Based on the Jakes Model

This paper presents an improved Rayleigh fading channel simulation method based on the Jakes' fading model. The approach involves several modifications and enhancements to the original Jakes model, resulting in more accurate and reliable simulation outcomes. During the simulation process, we account for key channel characteristics including multipath fading, Doppler frequency shift, and phase variations to realistically emulate actual wireless channel conditions. The implementation typically involves generating multiple oscillators with properly weighted amplitudes and random phases, where the number of oscillators corresponds to the number of scatterers in the propagation environment. Key algorithmic improvements include optimized Doppler spectrum shaping and enhanced phase randomization techniques. Through this enhanced simulation methodology, we can better understand and analyze the performance characteristics of Rayleigh fading channels, providing valuable insights for the design and optimization of wireless communication systems.
