Abstract
The IEEE 802.15.4 physical layer research is fascinated area of research and lots of research are being carried out on it. Several researches are working on to make Zigbee technology better and better in terms of error probability or end to end performance. The end to end performance makes system reliable to save energy for which IEEE 802.15.4 standard known. In this paper spatial diversity using multiple inputs multiple output (MIMO) technology is adopted to enhance the performance of the Zigbee technology. In addition of proposed spatial diversity architecture O-QPSK is adopted which better perform with the standard than other modulation techniques. The proposed system is tested for transmitters and receiver considering 2, and 4 antenna pairs and found better results.
