Abstract: The various embodiments herein provide a Uniform Circular Displaced Sensor Array (UC-DSA) system and method for measuring/estimating Direction of Arrival (DOA) of a wireless signal. The UC-DSA system comprises at least a set of two circular antenna arrays. The two circular antenna arrays have a number of elements. A Radio frequency (RF) receiver captures a wireless signal incident on a circular antenna array. A Direction of Arrival (DOA) estimator processes a received input signal and a Triangulation system provides the exact location of the source of the wireless signal. The two circular antenna arrays with the same number of elements are placed on different radii, and are shifted to have equal separation between inner elements and outer elements.

Abstract: A communication technique includes mapping an information character to two or more subsymbol waveforms to produce an analog waveform. The two or more subsymbol waveforms define the information character. Alternatively, robustness can be achieved wherein each subsymbol waveform represents the information character, so that the information character is redundant in the analog waveform. The likelihood of success in the subsequent decoding of such a waveform to produce the information character is increased due to the redundancy.
