This paper focuses on a modified echo canceller system developed to satisfy the requirements of long network time-delay in the Internet of Things. The NLMS algorithm used in it is modified to reduce the computational complexity with the characteristics of fast convergence speed and low steady-state mean-square error (MSE). Hardware platform and software program have been designed to verify this algorithm. The simulation results by MATLAB and practical system are presented in support of the feasibility and validity of the proposed algorithm and echo canceller system.
