It can attain a desirable balance between frequency and time localizations for narrow bandwidths. It is also MIMO friendly. In this paper, a comprehensive design and analysis have been made to evaluate the performance of MIMO (4×4) CP-OFDM and F-OFDM systems for message bits transmission using several digital modulation techniques (16-QAM, 16-PSK, 16-DPSK, 64-QAM, 64-PSK, and 64-DPSK), RA channel coding, different windowed (Hanning, Hamming, Blackman, Blackman-Harris, RRC) sinc FIR filters for length N = 513, and MMSE signal detection technique. From MATLAB based simulation results, it is observed that F-OFDM reduces spectrum leakage thus enhances spectrum efficiency than conventional CP-OFDM. F-OFDM based system offe...

This system can control water wastage for irrigation purpose by using wireless sensor network (WSN) and IoT. Each WSN node contains a unit of combined sensors which has been made by several external sensors such as soil moisture, soil pH, and temperature sensor along with Node MCU for data transmission in the cloud. Other nodes are distributed in the field to collect field data for different positions and this information is sent to the server. Data processing and analysis are performed according to the proposed algorithm. Obtained result as well as weather forecasting report is checked for three days from a developed android app. The accomplished result is sent to the farmers through SMS; depending upon the SMS, farmers take necessary steps for watering or not in the crops field ...

The scenario is unusual for the disables of developing countries because of their economic conditions. Moreover traditional powered wheelchair is not comfortable to all segments of the disable society because of their complexity. Several researchers have used sophisticated technologies to operate wheelchair such as voice controlled, head gesture controlled, remote controlled wheelchair for providing better flexibility. For being sophisticated technology Android is being used in mobile, TV or in smart watches.An app with mitigating required controlling facilities is implemented here that may provide a flexible movement of the certain disable community. This paper focuses on the system of PWM based Android Controlled Wheelchair.
