SCFDMA--simulation-and-analyzation
通过仿真和分析对比SCFDMA的性能和算法。This is a very simple baseband simulator for SC-FDMA system. This simulator is
part of the upcoming book “Single Carrier FDMA: A New Air Interface for Long
Term Evolution” (Wiley, Nov. 2008) which I co-authored with professor David J.
Goodman at Polytechnic University.
The purpose of this simulator is to give some concrete idea of how SC-FDMA
system works. It does lack many realistic and sophisticated features such as
channel coding, time-varying fading channel model, soft decision decoding, etc.
Regardless, I am hoping that it will help you understand SC-FDMA which is a
fairly new development in 3GPP LTE.
For information on SC-FDMA, go to SC-FDMA resource website at
http://hgmyung.googlepages.com/scfdma. If you have any question, comment,
or feedback, please visit the SC-FDMA discussion forum at
http://scfdma.freeforums.org/ and leave your comment.(This is a very simple baseband simulator for SC-FDMA system. This simulator is

梯度下降法是最早最简单，也是最为常用的最优化方法。梯度下降法实现简单，当目标函数是凸函数时，梯度下降法的解是全局解。一般情况下，其解不保证是全局最优解，梯度下降法的速度也未必是最快的。梯度下降法的优化思想是用当前位置负梯度方向作为搜索方向，因为该方向为当前位置的最快下降方向，所以也被称为是”最速下降法“。最速下降法越接近目标值，步长越小，前进越慢。(The gradient descent method is the earliest and most simple and most commonly used optimization method. The gradient descent method is simple to realize. When the objective function is a convex function, the solution of the gradient descent method is a global solution. In general, the solution is not guaranteed to be the global optimal solution, and the gradient descent method is not necessarily the fastest. The optimization idea of gradient descent method is to use the current position negative gradient direction as the search direction, because the direction is the fastest descending direction of the current position, so it is also called the steepest descent method. The faster the slowest descent approach is closer to the target, the smaller the step, the slower the progress.)

There is a trend to develop blind or semi-blind source extraction algorithms based on
second-order statistics, due to its low computation load and fast processing speed.
An important and primary work is done by Barros and Cichocki, who propose an
extraction algorithm based on a time delay. The algorithm is simple and fast, but its
performance is not satisfying. The paper extends their work and proposes a robust
algorithm based on eigenvalue decomposition of several delayed covariance matrices.
It is faster and has better performance, which is conˉrmed by theoretical analysis
and computer simulations.
