Two Classes of Modulation Schemes for Deep Space Communications». The higher- speed. Binary phase-shift keying. Quadrature phase-shift. Basic QPSK Modulator and Demodulator. After the data is split into the I and Q channels, each channel is modulated onto a carrier, just as in BPSK. QPSK modulation : (a) input binary signal in polar form, (b) signal decomposition into two independent signals, (c) transmitted signal, (d) transmitter, (e) receiver.

Unlike BPSK which is a DSBCS modulation scheme with digital information for the message. Use this object to modulate the input signal using the quadrature phase shift keying ( QPSK ) method.

A novel QPSK Modulator. Any modulation scheme uses finite number of different signals to. This process of modulation is generally called frequency-shift keying, FSK. Principle of QPSK modulator — in quadrature phase shift keying (QPSK), two successive bits in the data sequence are grouped together this reduces the bit rate of.
