نویسندگان
چکیده
The aim of this study is to evaluate the method for compensation magnetic field interference from mains, which consists primarily components with a frequency 50 (60) Hz and its multiples. setup compensates interfering using three Helmholtz coils, sensors, digital processing unit, power amplifiers. unit implements an adaptive least-mean-square (LMS) algorithm calculate currents through coils that are necessary compensation. prototype fully at 50, 150, 250, 350 down noise level sensor arrangement within 20 s reduces higher harmonics. overall reduction in rms value better than 28 dB, significantly achieved range 0 400 Hz.

Interference Cancellation in Adaptive Filtering through LMS Algorithm using TMS320C6713DSK
The scope of this paper is interference cancellation which is concerned with removal of noise superposed on speech signal. Interference cancelling makes use of an auxiliary or reference input derived from one or more sensor located in noise field where the signal is undetectable. This input is filtered from primary input containing both signal and interference. Adaptive filtering which are able...
متن کاملAdaptive Digital Beam Forming using LMS Algorithm
There is a need of Phased Array Antennas in applications such as wireless communication, RADAR systems. The radiation pattern for this type of antenna has to be narrower sharper in one direction and should have nulls in other directions. In order to achieve this, phased array antennas are designed in such a way so as to steer the beam in required direction automatically. One of the techniques d...
