Description: This paper investigates the design of joint frequency
offset and carrier phase estimation of a multi-frequency time division
multiple access (MF-TDMA) demodulator that is applied to
a digital video broadcasting—return channel system via satellite
(DVB-RCS). The proposed joint estimation algorithm is based on
the interpolation technique for two correlation values in the frequency
and phase domains. This simple interpolation technique
can significantly improve frequency and phase resolution capabilities
of the proposed technique without increasing the number of
the correlation values. In addition, the overall block diagram of a
digital communications receiver for DVB-RCS is presented, which
was designed using the proposed estimation algorithms.

Description: In this paper the reduction of Intersymbol Interference
(1 ) in mobile communication channels is addressed. A
well known technique for IS1 reduction is adaptive equalization
in which the time-varying characteristics of the mobile
channel is tracked by an adaptive algorithm. We compare
different adaptive strategies and equalizer structures with
respect to overall system performance in terms of computational
complexity, numerical stability, finite wordlength
effects, size and power consumption required for VLSI implementation. Platform: |
