MIMO 系统中 信号检测算法的比较 zf mmse ML(Performance of zero-forcing detectors over MIMO flat-correlated Ricean fading channels)

OBD标准协议，其中包含ISO-15031(OBD standard protocol, which contains ISO-15031)

这是一个关于ofdm在802.11协议下的源码，很有参考价值，希望对大家有用(This is a matter of OFDM in the 802.11 protocol under the source, a good reference, in the hope that useful)

TOA算法C代码(Keil) 一对一(TOA)

本源码是本人工作之余码的，CC2540低功耗蓝牙的notify工作方式总结，这源码是很好的理解notify例子，代码中有注释，希望对大家有所帮助(The source code is my spare time, notify work CC2540 Bluetooth low energy summary, this source is well understood notify example, the code notes, we hope to help)

角谱--VCSEL发出的光，经过透镜耦合进入光纤，仿真给出光由VCSEL进过透镜进入光纤的过程(Angular spectrum)

数字基带系统,运行无码间干扰数字基带传输特性及眼图的程序，观察所有的结果，对结果做出分析(Digital base-band system, running without inter-symbol interference digital base-band transmission characteristics and the eye diagram of the procedure, observe all the results of an analysis of the results)

在AWGN信号下，实现pi-4 QPSK调制解调(pi-4 QPSK modulation and demodulation)

说明：  利用通信系统中调制信号的循环平稳特性,对频谱空洞进行检测,提升频谱感知技术在低信噪比下的性能。实验结果表明:与传统能量检测方法相比,采用循环特征检测方法改善了认知无线电中频谱空洞的检测能力。(Based on the cyclostationarity of modulation signals, spectrum hole is detected, aiming at the improve- ment of the performance of spectrum sensing in low SNR situation. The results show that comparing with the tra- ditional energy detection technique, cyclostationarity-based spectrum sensing technique has greatly improved the detective ability in cognitive radio.)

说明：  ：为了论证高斯最小频移键控(GMSK)信号在时域和频域的相互关系，分析了GMSK信 号调制原理和滤波器传递函数，建立了GMSK调制和解调模型。(: In order to demonstrate Gaussian Minimum Shift Keying (GMSK) signal in time domain and frequency domain, the relationship between the analysis of GMSK signal modulation principle and the filter transfer function established model for GMSK modulation and demodulation.)
