A Low-Complexity Method to Generate Delay Power Profile in Wideband High Frequency Channel Simulator

摘要：

Delay power profile (DPP) characterizes the delay dispersion in wide-band high frequency (VVBHF) channels, which determines whether the VVBHF channel simulator can be used for the evaluation of WBHF communication systems. Newtons iterative method is commonly used to generate DPP for WBHF channels. But it has large computational complexity, so is not fit for applying to the implementation of WBHF channel simulators. We propose a new method to generate DPP based on look-up table. Compared to Newtons iterative method, Look-up table needs fewer multiplications and additions operations and avoids log operations, having lower computational complexity. Simulation results demonstrate that the decline of precision of DPP brought by look-up table can be neglected if the memory resources are great
