Abstract

Validity of the standard Gaussian approximation (SGA) for modeling multi user interference (MUI) in impulse radio ultra wide band (IR-UWB) systems which do not implement power control is investigated. Analysis focuses on the case of UWB systems adopting binary pulse position modulation (2PPM) with a time hopping (TH) code division multiple access scheme. Theoretical predictions are compared vs. simulation outputs in order to quantify limitations of the SGA hypothesis.

功率不平衡超宽带系统中的多用户干扰:分析与验证

研究了不进行功率控制的脉冲无线电超宽带(IR-UWB)系统中标准高斯近似(SGA)多用户干扰建模的有效性。重点分析了采用二进制脉冲位置调制(2PPM)和跳时(TH)码分多址方案的超宽带系统。为了量化SGA假设的局限性，将理论预测与模拟输出进行比较。
