Description: 蚂蚁算法的matlab实现规则来源于大自然的进化。而大自然的进化根据刚才讲的也体现为多样性和正反馈的巧妙结合。而这样的巧妙结合又是为什么呢？为什么在你眼前呈现的世界是如此栩栩如生呢？答案在于环境造就了这一切，之所以你看到栩栩如生的世界，是因为那些不能够适应环境的多样性与正反馈的结合都已经死掉了，被环境淘汰了！-Ant Algorithm matlab from the realization of the rules of nature and evolution. The evolutionary nature of the basis of the speakers also reflected in the diversity and the unique combination of positive feedback. This ingenious combination is Why? Why is presented in front of your eyes the world is so lifelike it? The answer lies in the environment has created all this, because you see life-like world, is because those who could not adapt to the environment of diversity and the combination of positive feedback have been dead and was out of the environment!

Description: LTE链路级的仿真，非常的全面。考虑了现有LTE的大部分技术。MATLAB仿真，有些功能是用C代码写的。http://www.pudn.com/downloads240/sourcecode/comm/wireless/detail1121790.html
的内容的最新版本。-The LTE Link Level simulator simulator is provided with a test simulation scenario that can be used to verify that the simulator runs in the expected way.
In the main directory you can execute the LTE_sim_batch_quick_test MATLAB script. This script provides a means to
test the performance of an LTE transmission on an uncorrelated PedB channel and flat Rayleigh channel for several transmission modes. Since currently the feedback calculation for the Closed Loop Spatial Multiplexing (CLSM) mode is not implemented, only the Single-Input Single-Output (SISO), Transmission Diversity (TxD) and Open Loop Spatial Multiplexing (OLSM) modes are simulated.

Description: An adaptive transmit diversity scheme with quadrant phase constraining feedback is proposed in this
paper. With simple linear operations at both transmitter and receiver, the proposed algorithm can achieve better
system performances with only 2M − 2 bits of feedback information for systems with M transmit antennas.
Theoretical performance bounds of the proposed transmit diversity scheme are derived. Simulation examples and
theoretical analyses show that the proposed transmit diversity scheme outperforms not only the conventional openloop
transmit diversity techniques, but also some closed-loop transmit diversity techniques with more information
transmitted in the feedback channel.-An adaptive transmit diversity scheme with quadrant phase constraining feedback is proposed in this

Description: In a multiple transmit antenna, single antenna per receiver downlink channel with limited channel state feedback, we consider the following question: given a constraint on the total system-wide feedback load, is it referable to get low-rate/coarse channel feedback from a large number of receivers or high-rate/high-quality feedback from a smaller number of receivers? Acquiring feedback from many receivers allows multi-user diversity to be exploited, while high-rate feedback allows
for very precise selection of beamforming directions. We show that there is a strong preference for obtaining high-quality feedback, and that obtaining near-perfect channel information from as many receivers as possible provides a significantly larger sum rate than collecting a few feedback bits from a large number of users.
