Receiver cancellation of radar in radio

Global pressure to use spectrum more efficiently has sparked a great deal of research to mitigate spectral and spatial congestion between radar and radio systems operating in a shared spectrum access environment. This paper summarizes an algorithmic method of interference cancellation that enables the radar and radio to operate with reduced spatial and spectral separation. These performance improvements are achieved by modeling the measured spectral broadening due to nonlinear effects at the radar transmitter and cancelling this out-of-band interference at the communications receiver. Subsampling to address hardware constraints on receiver bandwidth and to achieve data (complexity) reduction is shown to be feasible.
