matlab环境下用simulink模拟BPSK扩频解扩过程(matlab environment simulation BPSK spreading despreading process using simulink)

说明：  Turbo code primer用于通信系统里编码译码，误码率小，但复杂度比较高。(Turbo code primer is used for coding and decoding in communication systems, with low bit error rate but high complexity.)

包括 MUSIC算法，ESPRIT算法 ROOT-MUSIC算法，FMCW调频连续波雷达的测距测角，是本科毕设的题目。( Including the MUSIC algorithm, ESPRIT algorithm ROOT-MUSIC algorithm, FMCW frequency modulated continuous wave radar range and angular measurements, The title of the commercial is undergraduate course yo.)

说明：  模糊综合评判计算程序 模糊综合评判的过程：1、灰色关联分析，求权重（程序见Relation）；2、模糊聚类分析，划分等级（程序见F_class）；3、隶属度计算，求隶属函数（程序见Subjection和subject）；4、模糊综合评判，计算各单元等级（程序见F_judge）。(Fuzzy comprehensive evaluation matlab code The process of fuzzy comprehensive evaluation: 1. Grey relational analysis to get weight (see Relation for program); 2. Fuzzy clustering analysis to divide ranks (see F_class for program); 3. Membership degree calculation to get membership function (see Subjection and subject for program); 4. Fuzzy comprehensive evaluation to calculate each unit grade (see F_judge for program).)
