Abstract
In this thesis, the quadrature-quadrature phase shift keying (Q^2PSK) signals over
the fading multipath channels will be analyzed. In the fading channels, inter-symbol interference (ISI) and cross-symbol interference (CSI) will be induced.
Those are relative to the pulse shapes of Q^2PSK signals. Hence, bit error probability (BEP) both for SB's and CL's schemes will be compared here. Moreover,
dual-Q^2PSK signal will be considered here. It transmits two independent Q^2PSK
signal carried by two central frequencies with a close separation at the same time.
Hence, the inter-carrier interference (ICI) will be induced. The BEP and spectral
efficiency both for SB's and CL's dual-scheme will be compared here. Furthermore,
{16QAM}^2 signals will also be compared too. Like dual-Q^2PSK signals, {16QAM}^2
signals was modulated in the same way like except that two 16QAM signals are
in place of two Q^2PSK signals. Both of them have the same transmitting bit rate
and so will be analyzed here.
