Offset quadrature phase shift keying modulation
y = oqpskmod(x)
y = oqpskmod(x,ini_phase)
y = oqpskmod(x) outputs
the complex envelope
y of the modulation of the
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.
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.
