Abstract: Wavelets are alternative building kernels of the multicarrier systems, such as the orthogonal frequency division multiplexing (OFDM). The wavelets can be designed by changing the parent basis functions or constructing new filters. Some two new wavelets are considered for multicarrier design; one is designed using raised-cosine functions while the other was constructed using ideal filters. The spectrums of raised-cosine wavelet filters are controlled by a roll-off factor which leads to many distorting sidelobes. The second family of wavelet, which the raised-cosine wavelet is compared to, have no distorting sidelobes. It will be shown that raised-cosine wavelets are less suitable for multicarrier design in multicarrier environment, in terms of BER when compared to the wavelet constructed from the ideal filter.

Abstract: Tuberculosis (TB) is second only to HIV/AIDS as the greatest killer worldwide due to a single infectious agent, and is one of the top killers among infectious diseases in Malaysia. In Malaysia, the TB incidences are increasing every year. Although the TB treatment success rate is increasing, the number is still not very promising compared to those in neighbouring countries. A study showed that patients treated without close observation by the hospital have a substantially higher risk of adverse outcome. The study also showed that a large proportion of unsuccessful treated cases could be identified and prevented at an earlier stage if the patients are closely observed by the hospital. As a result, we initiated a project called “Wellness Community: M-Health for TB patients” in an effort to enable the hospital to closely monitor and communicate with TB patients by utilizing information and communications technology. We developed a prototype of M-Health system which deploys push and pull t
