摘要/Abstract

摘要： 正弦波叠加法是生成衰落信道的有效方法,但生成高效率的信道模拟器需要以牺牲模拟器精度为代价。本文结合查表法和三角函数快速生成法对现有高精度平坦Rice信道模拟器进行改造,设计了一种高效平坦Rice信道模拟器。理论分析和仿真结果表明:该模拟器能在精度基本保持不变的情况下大幅度减小运算复杂度,提高仿真效率,有较强的实用性。

关键词: Rice衰落, 正弦波叠加法, 查表法, 模拟器

Abstract: Sum-of-sinusoids method is an effective way to generate fading channels,but the high-accuracy simulator is often at the expense oflow efficiency.Based on the table look-up method and fast trigonometric function,a novel flat Ricefading channel simulator is presented.Corresponding theoretical analysis and simulation results reflect that the simulator both have high velocity and high precision.

Key words: Rice fading, sum-of-sinusoids method, table look-upmethod, simulator
