The Institute would like to congratulate its very own, Dr. Charleston Dale M. Ambatali, on being the recipient of the Outstanding Paper Award for his paper entitled “Adaptive Parallelization of Time-Varying Dispersive Channels Using the Power Waveforming Framework,” during the 4th International Conference on Mobile Military Maritime IT Convergence (ICMIC) in Cebu, Philippines.
His paper’s abstract reads:
The power waveforming (PW) technique is conceptualized to maximize energy transfer from a transmitter to an intended receiver communicating over a scatteringrich or dispersive wireless channel. To achieve this, the PW technique measures the channel impulse response, converts it into a Toeplitz matrix, and solves the eigenvector that corresponds to the maximum eigenvalue. Using the same framework, it can be shown that a dispersive channel, wireless or wired, can be parallelized to increase the information transfer throughput, but sacrificing robustness against noise. This is done by exploiting the vector space formed from the CIR’s Toeplitz matrix. Its basis can be exploited as parallel waveforms that can be transmitted simultaneously, effectively turning a dispersive channel into multiple single channels. In this paper, we establish this expanded framework and analyze the resulting bit error rate when it is performed.
