Abstract

Telecommunication system is one of the major components in industry. It can be summarized as the transmission, reception, and processing of information between two or more locations, using either digital or analogue transmission. Wireless technologies become essential when guided media connections are difficult to provide economically. Wireless communication system affected by external (atmosphere) factors. Studies need to be done at certain places before actual communication system been implemented. The wireless transmissions over large water areas are different as compared to transmission over land in term of propagation conditions, radio wave reflection over water and ducting, which make them more difficult to design. However, they are very essential to remote-island or off-shore location to communicate with offices on main land. The main objective of this project is to develop a MATLAB simulation for QPSK that considered external factors in radio transmission. The analysis carried out was on BER performance for QPSK system, phasor and constellation analysis. This analysis is to determine that the simulation is well defined with the theoretical value. Factors involved in determining system performance such as multipath fading and AWGN also has been considered. The simulation output of the Maximal Ratio Combining (MRC) Space Diversity configuration for multiple receive antennas which shows the improvement in the received signal is also been analyzed.
