For researchers, denoising of Magnetic Resonance (MR) image is a greatest challenge in digital image processing. In this paper, the impulse noise and Rician noise in the medical MR images are removed by using Bilateral Filter (BF). The novel approaches are presented in this paper; Enhanced grasshopper optimization algorithm (EGOA) is used to optimize the BF parameters. To simulate the medical MR images...
Power amplifier is an essential component in every wireless communication system, but exhibits nonlinearity. A high power amplifier gets saturated, when the amplitude or power of the input signal is very large. Nonlinearity in power amplifier is due to the combined effect of amplitude distortion, phase distortion and memory effect. By using power amplifier linearization method, efficiency of the power...
