Usb通信程序开发示例，讲述如何开发一个USB应用用程序

It is very useful for everyone

资源描述本例程通过两台usrp实现数据的发送和接收，创建MIMO信道下的OFDM通信，需要多台USRP的参与，直观理解通信收发的原理，适合初学者学习使用。用户可以再此基础上设计大规模mimo的5G通信原型。软件无线电参考了这样一个技术：通用硬件平台上运行软件模块，用于实现无线功能。结合NI USRP硬件和NI LabVIEW软件的优势，提供了满足多功能需求且灵活性强的快速通信原型平台，适用于物理层设计、无线信号录制与回放、通信情报、算法验证等应用

引入PEG（Progressive-edge-growth）算法来构造适合线性时间编码的LDPC校验矩阵，译码时采用简化最小和Min-Sum译码算法实现简化译码．仿真结果表明，该方法能够构造适合LDPC码的线性时间编码的下三角校验矩阵日，并且用此方法构造的LDPC码性能非常接近原来PEG算法构造的LDPC码．同时通过采用最小和Min-Sum算法降低译码复杂度．-The introduction of PEG (Progressive-edge-growth) algorithm to construct suitable for linear time encoding of LDPC check matrix, decoding simplified when the smallest and the Min-Sum decoding algorithm decoding simplified. Simulation results show that this method can construct LDPC codes suitable for linear time encoding on lower triangular calibration matrix, and constructed using this method the performance of LDPC code is very close to the original PEG algorithm constructed LDPC codes. At the same time through the use of the smallest and the Min-Sum decoding algorithm to reduce complexity.
