Implement a Portable Smart Device for Elder Health Care
Ching-Sung Wang, S. M. Chen
American Journal of Electrical and Electronic Engineering. 2020 8 (3). doi: 10.12691/ajeee-8-3-5
Keywords: automatic window glass opening device, emergency rescue, sensor, water level detection, abnormal gas detection
Context: ...e art sensor technology, the intelligent sensor comes out to be capable of recording aged people’s essential tremor spectrum via fast Fourier transform (FFT) and their daily exercise simultaneously. With gathering both of detecting information, the sensor would be trans...

Characterization of Orthogonal Frequency Division Multiplexing (OFDM) Communication Links
Rahmon Kamorudeen Adewale, Ogunti Erastus Olarewaju, Apena Waliu Olalekan
American Journal of Electrical and Electronic Engineering. 2020 8 (3). doi: 10.12691/ajeee-8-3-4
Keywords: OFDM, BER, M-PSK, M-QAM, FFT, AWGN channel, Rayleigh channel, Rician channel
Context: ...multipath fading channels in OFDM system. Bit error rate (BER) was used to evaluate the performance of the system; the number of fast Fourier transform (FFT) points used during the transmission was also examined. The results showed that for all the channels, lower order...
