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.
