Joint
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.

ZigBeeIEEE
The implementation was built on Matlab/Simulink using
fundamental components in Simulink to demonstrate how
reliably complex modulation schemes can be built, cost
effectively and efficiently [5]. The design of ZigBee
transmitter using MSK modulation is shown in the Figure 1.
Here we map input data bits to 8-chip PN sequences to be
transmitted and results in a chip rate of two mega chips per
second. After that, resultant chip sequence is send to the serial
to parallel converter. It is used here to separate the odd and
even bit indexed chips. Following this bipolar data formatting
is performed and signal modulated with a 2.4 GHz carrier on
the In Phase and QuadraturePhase data stream and adds it to
get the required transmitter output signal.
