  • MIMO-GMC系统中Turbo译码器的设计及FPGA实现

    Turbo码是一类并行级联的系统卷积码,它是在综合级联码、最大后验概率(MAP)译码、软输入软输出及迭代译码等理论基础上的一种创新。Turbo码的基本原理是通过对编码器结构的巧妙设计,多个子码通过交织器隔离进行并行级联编码输出,增大了码距。译码器则以类似内燃机引擎废气反复利用的机理进行迭代译码以反复利用有效信息流,从而获得卓越的纠错能力。计算机仿真表明,Turbo码不但在加性高斯噪声信道下性能优越,而且具有很强的抗衰落、抗干扰能力,当交织长度足够长时,其纠错性能接近香农极限。 FPGA(FieldProgrammableGateArray),即现场可编程门阵列,是在PAL、GAL、EPLD等可编程器件的基础上进一步发展的产物。FPGA技术具有大规模、高集成度、高可靠性、设计周期短、投资小、灵活性强等优点,逐步成为复杂数字硬件电路设计的理想选择。 本论文以东南大学移动通信实验室B3G课题组提出的“支持多天线的广义多载波无线传输技术”(MIMO-GMC)为背景,分析了Turbo译码算法,并针对MIMO-GMC系统的迭代接收机中所采用的外信息保留和联合检测译码迭代的特点,完成了采用滑动窗Log-MAP算法的软输入、软输出的Turbo译码器的设计。整个译码器模块的设计采用Verilog语言描述,并在VirtexⅡPro系列FPGA芯片上实现。

  • 基于LDPC的MIMO卫星扩频通信系统

    在卫星通信系统中应用MIMO技术,主要面临同道干扰和噪声两个问题。文中介绍了克服同道干扰的MIMO卫星通信线性检测系统,并为解决上述问题,在输入端引入扩频技术和接近香农极限的LDPC编码,而在输出端进行解扩和译码,既减小了同道干扰,又明显削弱了噪声,从而实现了良好的性能。

  • MIMO雷达DOA估计算法研究

      近年来,多输入多输出(MIMO)雷达受到国内外科研人员的广泛关注。这种新体制雷达能够在时域、频域、空域、码域获取更加丰富的目标和环境信息,尤其是MIMO雷达的空间分集和信号分集特性在提高雷达的检测与参数估计性能等方面具有很大的优越性,能够突破传统雷达的性能限制。论文围绕MIMO雷达空间分集与信号分集特性,针对目标分辨与定位问题提出了MIMO雷达DOA估计的新算法,利用MIMO雷达实验系统的实验数据验证了新算法的有效性。

  • This a Bayesian ICA algorithm for the linear instantaneous mixing model with additive Gaussian noise

    This a Bayesian ICA algorithm for the linear instantaneous mixing model with additive Gaussian noise [1]. The inference problem is solved by ML-II, i.e. the sources are found by integration over the source posterior and the noise covariance and mixing matrix are found by maximization of the marginal likelihood [1]. The sufficient statistics are estimated by either variational mean field theory with the linear response correction or by adaptive TAP mean field theory [2,3]. The mean field equations are solved by a belief propagation method [4] or sequential iteration. The computational complexity is N M^3, where N is the number of time samples and M the number of sources.

    This model is just testing an idea of MIMO, which IEEE802.11n will have. But I havo not seen the standard, I tried to make it with 11a. Actually this model would not work in real world, because the preambles were not designed to solve the MIMO feature. But this model may be useful to get some idea to start to design a PHY with MIMO.

  • 尊敬的站长: 鄙人是研究MIMO通信系统的一名研究生

    尊敬的站长: 鄙人是研究MIMO通信系统的一名研究生,经人介绍找到贵站,感觉贵网站资料有鄙人一直苦苦搜索的内容,但苦于自己不是专门的编程人员,对源码所知甚少,仅上传4篇有关我研究专业的英文版论文,均为2005年下半年及06年IEEE检索文章(国内网站均未见中文版本,对于研究MCMC(蒙特卡罗-马尔科夫检测方法)方法有很大帮助),希望能予以录用,给予下载权限(本人只需很少资源有寥寥几个便足矣)。盼回信告之!
