Abstract :
In this paper, Wavelet based Orthogonal Frequency Division Multiplexing (WOFDM) is proposed as the primary modulation technique for Multi-Input Multi-Output (MIMO) Wireless Sensor Networks (WSNs) based on Vertical Bell Labs Layered Space-Time (V-BLAST) architecture. The BER and energy performance of WOFDM is analyzed and compared with other well-known modulation techniques. By exploiting the properties of WOFDM such as one dimensional constellation and low Peak-to-Average-Power Ratio (PAPR), simpler RF section can be designed for energy-efficient and high data-rate WSNs.
