Abstract
In this paper, we propose an adaptive modulation approach in an adaptive way guaranteeing signal interpretation quality and energy efficiency in wireless multimedia sensor networks. The performance of QPSK, QAM with OFDM are compared and designed for diverse channel environments. MATLAB Simulink simulations illustrated the transmitting and receiving performance based on the bit error rate, Discrete-Time Scatter, Spectrum Scope, and constellation diagram.
