摘要
基于构建的Gold码生成系统,从码互相关特性、功率谱密度分布和码时钟泄漏方面对平衡码和非平衡码进行了仿真研究。相较于非平衡码,平衡码具有较小的互相关旁瓣值,功率谱分布幅值范围小,克服了码时钟泄漏,能极大地抑制载波泄漏,具有较高的功率效率和带宽效率。
Based on the built Gold code system,the cross-correlation characteristics,the power spectral density distribution and the clock leakage of the balanced code have been compared with that of the unbalanced code by simulations.The balanced code has a smaller cross-correlation sidelobe value and a narrower amplitude range of power spectral distribution than the unbalanced code.At the same time,the balanced code with high power efficiency and bandwidth efficiency could overcome the code clock leakage and suppress the carrier leakage significantly.
