Description: 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. Platform: |
