Numerical Techniques at Millimeter Wave Frequencies for Wireless Body Area Networks-A Review

Khaleda Ali

Millimeter wave frequencies offering higher bandwidth, reliable performance and unlicensed use has become an alluring option for the future of wireless body area networks. This paper discusses about the scopes and limitations of different numerical techniques at millimeter wave frequencies for analyzing propagation in such networks. It is observed that at this spectrum, Finite difference time domain technique though computationally expensive, can be the most ideal tool for accurate channel estimation. For efficient use of resources a customized version of FDTD has also been presented in this paper. Convergence test of the FDTD algorithm has also been performed to evaluate the optimum discretization step which ensures accuracy and efficiency. Log in to use Ginger Limited mode discretization ×
