ABSTRACT: This paper presents novel
information-theoretic PHY layer performance improvement for combating the
system fading effects in wireless terrestrial communication applications.
Robust space-time system strategies in cooperation with the high performance
unpunctured serially concatenated codes have been jointly employed. The
wireless terrestrial system also uses M-ary quadrature amplitude modulation
(QAM) signaling to develop a well-established system modeling for
multiple-input single-output (MISO) and multiple-input multiple-output (MIMO)
analysis. This research also undertakes the analytical evaluation of time delay
estimation in the presence of additive white Gaussian noise (AWGN) in multipath
areas. The objective of this investigation is to develop
mathematically-oriented estimations intended for a suitable employment in
terrestrial communications. This model considers the problem of overlapping the
terrestrial signals arrival-times estimation from a noisy received waveform in order to develop a
system model for terrestrial TDE.
