    Abstract: The present subject matter relates to a road information exchange system (100). The road information exchange system (100) comprises a plurality of Guided Autonomous Information Network (GAIN) units (102) installed on a road. Each GAIN unit (102) communicates with another GAIN unit (102) of the plurality of GAIN units (102) to divide the road into virtual lanes by formation of microgrids and further communicates with a vehicle passing through the road information exchange system (100).

    Abstract: A voice communication system (100) is described. The voice communication system (100) may include an audio engine (112) and a mapping engine (114). The audio engine (112) may cancel ambient noise from a plurality of acoustic signals, to obtain a first set of signals. Further, the audio engine (112) may determine a number of acoustic signals in the first set of acoustic signals and a number of sound sources pertaining to the first set of acoustic signals. The mapping engine (114) may suppress noise from each of the first set of acoustic signals to obtain a noise free set of acoustic signals. In addition, the mapping engine (114) may identify a primary acoustic signal from amongst the noise free set of acoustic signals by mapping each noise free acoustic signal to a corresponding sound source.
