计算连续方波信号的付里叶变换，与付里叶系数(consecutive terms of the square wave signal Fourier transform, and the Fourier coefficients)

Generalized Givens Transformation and its Application

In Modulation schemes such as OFDM transmitter time domain signal will have higher PAPR, which leads to various distortions in the transmitter chain and degradation of system performance i.e. BER/PER. Also requires highly linear power amplifier which increases cost of the system. PAPR is ratio of peak power to average power of time domain complex baseband signal which is to be transmitted. We will discuss PAPR reduction techniques below.

波束形成相关程序，包括窄带常规波束形成及MVDR波束形成的波束图和方位估计仿真，还有宽带小数时延常规波束形成器的仿真。本程序主要基于水声背景，模型是最简单的线列阵，但对其他阵型只要修改至相应方向相应向量即可，对雷达和语音阵列信号处理修改相应波速频率即可。(Beam forming procedures, including conventional narrowband beamforming and beamforming MVDR beam pattern and orientation estimation simulation, as well as conventional broadband fractional delay beamformer simulation. This program is mainly based on the background the sound of water, the model is the simplest linear array, but as long as the formation of other modifications to the corresponding direction vector corresponding to, radar array signal processing and voice modify the velocity frequency.)

对码元序列进行基带成型滤波，来减少码间串扰，采用的是升余弦滚降滤波器，可以通过更改参数的方式来更改成根升余弦滚降滤波器(Symbol sequence baseband shaping filter to reduce inter-symbol interference, raised cosine roll-off filter, you can change the parameters to change into a root raised cosine roll-off filter)
