Application of forward correction (FEC) negatively effects the transmission using 8PSK and QPSK modulation types resulting in decrease of the transmission quality.
Received signal noise causes variations in the received modulation levels--causing, for example, the phases of the QPSK signal to be other than the exact 0-, 90-, 180-, or 270-degree values.
We observe the transmission of BPSK and QPSK signals over [eta]-[mu] fading channel.

Four Nyquist-shaped 25-GBd quadrature phase-shift keying (QPSK) modulation channels were successfully multiplexed to a 200-Gb/s super-channel.
In [7], a kind of all-digital phase-locked loop (ADPLL) for QPSK combining a first-order frequency recovery loop based on feedback control with a second-order phase-locked loop is proposed.
To demonstrate the phase error effect on conventional demodulator, gain error and frequency shift have been removed from the incoming QPSK signal as in (1) to ease the calculation.
For 3X3 MIMO communication systems, analysis of full-rate linear and space-time block code under a Rayleigh flat-fading environment has been carried out in [9] by using linear MMSE and ML receivers to minimize the average symbol error rate (SER) for a QPSK transmitted signal.
