OFDM_01

Derive the theoretical 16QAM bit error rate (BER) with Gray coded constellation mapping in AWGN

DS-EV证据理论消除了当不同证据冲突过大时，判决的错误型。自己论文里所用的代码，用在认知无线电中。函数文件。(DS-EV evidence theory eliminate the wrong judgement when supplied evidence have strong contradictory This file has been used in my thesis in CR field. hope it can help you.)

多用户检测算法的比较，包括解相关、MMSE、SIC、PIC(Multi-user detection algorithm, including the decorrelating, MMSE, SIC, PIC)

D-S证据理论的MATLAB代码函数文件 根据D-S理论，可以进行模式分类，消除不确定性。并附有能量检测的D-S判断函数文件、自己论文里的代码，希望对你有用(Code function file of D-S evidence theory in MATLAB. it can accomplish mode classification and eliminate uncertainty. besides that it includes that D-S operation in energy detection technology function file. this file has been used in my thesis, holp it can help you.)

说明：  QPSK通信调治与解调DSP开发C++代码，可以在TI DSP上实现(QPSK modulation and demodulation communications DSP development of C code can achieve TI DSP)

求阵列天线方向图，矩形栅格点平面阵方向图。(Array antenna pattern)

说明：  实现雷达的空间谱估计，采用MUSIC算法，可实现多目标的位置估计(Space spectrum estimation of radar)

代码为对ofdm信号进行二次插值的仿真代码(Code for OFDM signals, quadratic interpolation of the simulation code)

说明：  我在美国公司用的CA code GPS toolbox(this is matlab toolbox I write and use in my company for simulating a CA code in GPS)

To understand the transmission scheme for QPSK modulation. To design a simple transceiver structure operating in a noisy channel.
