Enhanced partial transmit sequence technique with improved partitioning and phase factor methods for orthogonal frequency division multiplexing systems
Orthogonal Frequency-Division Multiplexing (OFDM) is an important technology that enables transmission at high data rates. However, a major problem of OFDM systems is the high peak-to-average power ratio (PAPR) of OFDM ...
Wireless heart rhythm abnormality monitoring kit based on Raspberry PI
According to statistics, heart diseases kill about 29,360 people every year in Malaysia
and about 600,000 people in America. Heart monitoring kits are only available for
bedridden patients, and the traditional heart ...
Development of new model for multiwavelet-based OFDM over wireless channel and its implementation in FPGA
Orthogonal Frequency-Division Multiplexing (OFDM) has been widely utilized in the field of high speed communication systems, due to its prominent features. However, it is prone to impairments such as Inter-Symbol Interference ...
Dual downlink signals level balancing methodology before reception of dual receiver antennas for LTE UE test conformance
This thesis presents alternative and more significant cost save approach to resolve the dual downlink signal level balancing issue before reception of dual receiver antennas for LTE user equipment (UE) test conformance. ...
OFDM system based on framelet transform and radon mapping with FPGA implementation
Increasing demands for high speed data transmission and unrivalled spectral efficiency are drivers for the current and future wireless communication systems. Orthogonal Frequency Division Multiplexing (OFDM) has been ...
Angle of arrival estimation system for radiation pattern reconfigurable antenna with modified gaussian membership function
This research focuses on developing angle of arrival (AOA) estimation system
(AES) through incoming received signal strength indication (RSSI). Proposed AES is
developing on a single board computer (SBC) using an open ...
Optical millimeter waves signal generation using stimulated brillouin scattering approach for radio over fibre system
Mm-waves are vital to overcome the issues of spectral congestion at low-frequency ranges and to acknowledge the performance of the Radio-over-Fibre (RoF) systems due to their large bandwidth, low cost and low attenuation. ...
Wifi-UHF transceiver design for 650-680 MHZ television white space (TVWS) spectrum application
