基于Fast-ICA的CDMA信号扩频序列盲估计及性能分析
扩频序列盲估计 性能分析 Fast-ICA CDMA信号
2012/4/13
DS-CDMA分为长码和短码扩频2种扩频方式，已有的扩频序列盲估计算法只适用于短码扩频信号，不能完成长码扩频信号的扩频序列估计。对长码扩频CDMA信号的数学模型进行分析，提出了一种的新的基于Fast-ICA的多用户扩频序列盲估计方法并推导了算法的理论性能。该方法不仅能适用于长码扩频CDMA信号，而且对同步短码扩频CDMA信号也同样适用。理论分析和仿真结果验证了该方法的有效性。
对FAST TCP拥塞控制算法中的参数γ设置范围做了研究。首先，提出了一种基于控制理论的网络流量数学模型，对方程线性化之后进行了拉普拉斯变换，得到1个带负反馈的线性窗口拥塞控制系统。接着，根据Routh-Hurwitz判据对系统进行了二阶稳定分析。然后，针对1个、2个以及无穷多FAST数据流共享一条瓶颈链路的情况，分析了窗口控制参数γ在满足稳定条件下选择的范围，得出了参数γ满足稳定的充分条件。最后...
