Performance Analysis of MIMO Spatial Multiplexing on IEEE 802.15.4

In this paper, we apply MIMO spatial multiplexing scheme on IEEE 802.15.4 physical layer to increase the data rate. In our proposed system, zero forcing method is used as MIMO decoding scheme. Based on simulation result, BER performance of 802.15.4 with MIMO spatial multiplexing is better compare to the conventional 802.15.4.
