一种基于ofdm系统的qam软判决算法的研究与仿真，可以适用于LTE系统。

介绍了自适应滤波器去除噪声的原理和从强噪声背景中采用自适应滤波提取有用信号的方法，并对最小均方(LMS, Least Mean Squares)和递推最小二乘(RLS, Recursive Least Squares)两种基本自适应算法进行了算法原理、算法性能分析。计算机模拟仿真结果表明，这两种算法都能通过有效抑制各种干扰来提高强噪声背景中的信号。检测特性相比之下，RLS算法具有良好的收敛性能，除收敛速度快于LMS算法和NLMS算法以及稳定性强外，而且具有更高的起始收敛速率、更小的权噪声和更大的抑噪能力。

Tactically maneuvering targets are difficult to track since acceleration cannot be observed directly and the accelerations are induced by human control or an autonomous guidance system therefore they are not subject to deterministic models. A common tracking system is the two-state Kalman Filter with a Singer maneuver model where the second order statistics of acceleration is the same as a first order Markov process. The Singer model assumes a uniform probability distribution on the target s acceleration which is independent of the x and y direction. In practice, it is expected that targets have constant forward speed and an acceleration vector normal to the velocity vector, a condition not present in the Singer model. This paper extends the work of Singer by presenting a maneuver model which assumes constant forward speed and a probability distribution on the targets turn-rate
