Abstract Details

2015, Master of Science (MS), Ohio University, Electrical Engineering (Engineering and Technology).
M - ary Frequency shift keying (MFSK) is a modulation scheme in which power efficiency increases as the number of symbols (M) is increased in the system. But as M increases the bandwidth and the complexity of the system also increases. Multi- dimensional symbols are used to achieve power efficiency as well as bandwidth efficiency. Bi-orthogonal MFSK, using two and three tone combinatorial MFSK are the modulation schemes used in this thesis to achieve efficiency between the bandwidth and power. In this thesis 4,8,16 ary orthogonal and bi – orthogonal FSK modulation schemes are designed and simulated in an additive white Gaussian noise (AWGN) channel with coherent demodulation using MATLAB. The two and three tone combinatorial FSK are built using 4 and 8 ary bi-orthogonal signal set. The results calculated from the two and three tone combinatorial MFSK are compared with the bi- orthogonal MFSK to eval-uate the bit error performance and bandwidth efficiency of the system
