Making Cylinder code for matlab using top and bottom point with radius

IEEE802.11物理层OFDM仿真，做了QPSK和QAM两种调制方式和不同信道估计方式的对比图，信道包含瑞利衰落和高斯噪声(IEEE802.11 OFDM physical layer simulation, QPSK and QAM made ​ ​ two modulation methods and different ways of estimated channel comparison chart)

永磁同步电机(PMSM)的矢量控制仿真模型，速度环采用滑模变结构控制，仿真波形较好。(The vector control simulation model of permanent magnet synchronous motor (PMSM) adopts sliding mode variable structure control in speed loop, and the simulation waveform is good.)

本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16； 接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响 从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16 Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)
