Abstract Details

2010, Master of Science, Miami University, Computer Science and Systems Analysis.
The purpose of this research was to implement a software-defined radio based on a recently developed framework for constructing various spectrally-modulated, spectrally-encoded (SMSE) signals. Two candidate waveforms (MC-CDMA and TDCS) are selected to demonstrate the capabilities of the framework, and they are modulated using antipodal signaling. A transmitter and receiver are each implemented on separate digital signal processor starting kits (DSK). A channel simulator consisting of additive white Gaussian noise and narrowband BPSK interferers is implemented on an FPGA. Burst transmissions from transmitter to receiver through the channel simulator are conducted to evaluate the bit-error rate performance of the system. Results from floating point simulation, fixed point simulation and hardware implementation are presented. The bit-error results from the hardware implementation closely match theoretical results. Also, TDCS is shown to mitigate effects of narrowband interference compared to MC-CDMA.
