ZigBee simulink
no vote
Simulink implementation of ZigBee tranceiver with OQPSK modulation and halfsine pulse shaping. Implementation of transmitter using random integer generator and Direct Spread Spectrum Technique with pseudo sequence. And AWGN channel for transmission. Receiver is implemented with filters, DSSS despreading technique and OQPSK demodulator

ZigBee implementation is built on Matlab/Simulink using fundamental components in Simulink to demonstrate how reliably complex modulation schemes can be built, cost effectively and efficiently. The design of ZigBee transmitter using OQPSK modulation. 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.
