oqpskmod

Offset quadrature phase shift keying modulation

Syntax

y = oqpskmod(x)
y = oqpskmod(x,ini_phase)

Description

y = oqpskmod(x) outputs the complex envelope y of the modulation of the message signal x using offset quadrature phase shift keying (OQPSK) modulation. The message signal must consist of integers between 0 and 3. The function implicitly upsamples by a factor of 2 because OQPSK does not permit an odd number of samples per symbol. If x is a matrix with multiple rows, the function processes the columns independently.

y = oqpskmod(x,ini_phase) specifies the phase offset of the modulated signal in radians.
