How to demodulate PSK in Matlab?
z = pskdemod( y , M ) demodulates the input M-PSK signals y . M specifies the modulation order. z = pskdemod( y , M , phaseoffset ) specifies the phase offset of the M-PSK constellation. z = pskdemod( y , M , phaseoffset , symorder ) specifies the symbol order of the M-PSK constellation.
How to modulate a signal in Matlab?
y = modulate( x , fc , fs ) modulates the real message signal x with a carrier frequency fc and sample rate fs . If x is a matrix, the modulated signal is computed independently for each column and stored in the corresponding column of y . [ y , t ] = modulate( x , fc , fs ) also returns the internal time vector t .
