Abstract Details

2017, Master of Science, Miami University, Computational Science and Engineering.
This thesis proposes encoding information onto random distribution parameters so that the same exact signal may be used for both radar and communications, simultaneously. Orthogonal Frequency Division Multiplexing (OFDM) sub-carrier weights are used to transmit samples of a random distribution. Weibull and Rayleigh distributions are explored and friendly reception in simulation for Rayleigh achieved a bit error rate (BER) of 10-3. Assuming a worst case scenario where an eavesdropper is missing only one piece of information about the signal, we show that using at least 32 sub-carriers they are unable to achieve a BER less than 30% for both Weibull and Rayleigh distributions. Finally, experimental results show similar trends in penalization using a Weibull distribution
