离散信号与系统的MALAB实现。其中包括信号基本运算，移位，相加，相乘及变换。-Discrete signals and systems to achieve MALAB. Including basic computing signal, shift, add, multiply and transform.

cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used to calculate a whole range of scientific functions including sin, cos, tan, arctan, arcsin, arccos, sinh, cosh, tanh, arctanh, log, exp, square root a

实现了大数的创建，加减乘除，移位（左右），微分，积分等基本操作。-Realized the creation of tarsus, add, subtract, multiply and divide, shift (or so), differential, integral, and other basic operation

使用移位法实现数值的加减乘除基本的数学运算-Shift method to implement the value of add, subtract, multiply and divide

You can learn BPSK modulation in OFDM Systems BPSK means binary phase shift keying modulation. Basically OFDM uses fft/ifft modulation. and add cyclic shift and remove to cancel inter-symbol-interference.
