Effect of OFDM Signal Structure and Subcarrier Modulation on the Reduction of the Signal Peak Power
Kiambi, Stephen; Mwangi, Elijah; Kamucha, George (University of Nairobi, 2017)The problem of high ratio of peak-to-average power experienced in orthogonal-frequency-division-multiplexed signals remains a major challenge when it comes to practical realization of transmitters for such signals. This ... -
A rapid MRI reconstruction method based on compressive sampling and concomitant artifacts suppression
Kiragu, Henry; Mwangi, Elijah; Kamucha, George (University of Nairobi, 2018)In this paper, a proposed rapid Magnetic Resonance Imaging (MRI) reconstruction method is presented. The method is based on the compressibility of the images in the wavelet domain and suppression of the resulting artifacts. ...
