Abstract
WSN’s and WPAN technologies continue to develop rapidly with integration into numerous applications. The ever increasing demands on these systems require that radio transceiver extended their coverage area and adopt more efficient algorithms to full fill the requirements of new applications. In this paper, a unique application of Multiple Input Multiple Output (MIMO) technology is applied to the application of WSN’s in order to dynamically extend range and thus overall coverage area. The scheme incorporates multiple antennas with Dual Circular 32-QAM modulation for MB-OFDM based systems in order to increase the wireless communication range. Simulation results are then presented that have shown a significant improvement in the system performance in terms of the bit error rate and also signal to noise power ratio
