QPSK modulation and generating signals
Web solving this linear system in sine and cosine, one can express them in terms of the exponential function: For any complex number z ∈ : Web euler's formula, the definitions of the trigonometric functions and the standard identities for exponentials are sufficient to easily derive most trigonometric. Sin x = e i x − e − i x 2 i cos x = e i x + e − i x 2. Expz denotes the exponential function. Web relations between cosine, sine and exponential functions. Cosz = exp(iz) + exp( − iz) 2. (45) (46) (47) from these relations and the properties of exponential multiplication you can.
