Signal Processing / Communications
WPI expertise in signal processing, RF, GPS, and other broadband communications related system design has been the basis for highly focused work in practical, high impact applications such as wireless ("untethered") healthcare and urban geolocation (high resolution, ad hoc positioning and personnel location) for multiple first responder and critical mission scenarios. The department of Electrical and Computer Engineering leads the innovation in this area augmented by its own departmental focus areas e.g. The New England Center for Analog and Mixed Signal Design and multi-departmental focused research centers such as BEI.
Michalson/Matthews , U.S. patent pending, OFDM-based VHF/UHF modem - Utilizing Orthogonal Frequency Division Multiplexing methods public safety radio (Land Mobile Radio) infrastructure can provide reliable voice and data network capability for a range of medical applications esp. in rural locations. Additional feature to this invention is Voice over Internet Protocol (VoIP) data packet generation resulting in a local wireless WAN on the LMR infrastructure and multi-communication system interoperability.
Cyganski, U.S. Pat. No. 11/051,546; U.S. Pat. Pub. No. 20050213586, System and method to increase network throughput*- Dynamic allocation of bandwidth to manage Internet Protocol - Available Bit Rate (IP-ABR) data flows in a network.
Michalson, U.S. Pat. No. 10/459,376; U.S. Pat. Pub. No. 20040021515, Adaptive spatial temporal selective attenuator with restored phase - This invention addresses the important problem of interference in GPS signal reception esp. in situations involving pseudolites, i.e. locally transmitting pseudo satellites providing GPS-type signals.
Cyganski/Orr/Michalson/Duckworth , U.S. patent pending, Methods and apparatus for high resolution positioning - In addition to precision location in complex multi-path environments, reliable and potentially stealthy data communications capability is achieved utilizing Orthogonal Frequency Division Multiplexing (OFDM) modulation techniques within the MCUWB signal paradigm.
Michalson, U.S. Pat. No. 7,079,025 , Reconfigurable geolocation system - This invention provides an ability to locate or navigate with accuracy in situations in which reliable GPS signals or other radio-based navigational resources are unavailable via use of networked pseudolites, i.e. locally transmitting pseudo satellites providing GPS-type signals.
