浅海远程水声通信由于水声信道带来的严重多径干扰和衰落, 导致通信速率低、误码率高
以及接收端信噪比低等缺点。针对这一问题, 提出了一种比较有效的M 元线性调频(L FM ) 水声通
信技术。(Remote shallow water acoustic underwater communication channel because of the serious multi-path interference and fading, resulting in lower communication rate, error rate
And the receiver signal to noise ratio and low defects. To solve this problem, we propose a more effective M-ary linear FM (L FM) acoustic communication

(To provide the necessary design parameters for the actual motor control system, the modeling course of
voltage space vector pulse wide modulation(SVPWM)agrithmetic and AC motor under Matlab/Simulink environment
are introduced. The dynamic model of variable frequency speed regulating system based on vector control is
discussed according to the principle of SVPWM. The new method of realizing simulation, key problems and
results of the simulation are analyzed in detail. The experimental simulation results show that this system has
smaller fluctuations of voltage and torque, quicker response speed, and all of the indicators accord with the
performance of the actual motor. The simulation agrithmetic have value to realize controlling motor with digital
signal processing.
