Abstract

"This Phase 1 SBIR proposal addresses a new waveform for wireless communications for the US Army's Tactical Radio Communications Systems (TRCS). The evolving digital battlefield will require significantly higher communication data rates to supporttransmission of voice, video and data. New, spectrally efficient waveforms will be needed to accomplish this in the presence of existing communications systems and radios. With increasing demands on limited RF spectrum, more spectrally efficient waveformsthat can withstand in-channel and adjacent channel interference and jamming are required to allow the Army to fully perform its mission on today's digitized battlefield.These waveforms will need to be compatible with the Joint Tactical Radio System (JTRS) platforms being developed and as such will need to implemented in software.The waveform proposed herein is an advanced technology that has been matured under commercial development, and which has proved its capability to provide robust, high-efficiency communications in heavy interference and multipath environments. The waveformaccomplishes this by a synergistic combination of several enabling technologies, namely packetized time-division duplex (TDD) networking protocols, stacked carrier spread spectrum (SCSS) modulation formats, fast Fourier transform (FFT) based discretemultitone (DMT/OFDM) modulation formats, adaptive antenna arrays, blind adaptive spatial and spectral despreading (rece
