Abstract:
1. A method for interference reduction in transmission of at least two single carrier frequency continuous communication beams comprising: producing a first communication signal for a first wireless communication link; producing a second communication signal for a second wireless communication link; transmitting the first communication signal over a first continuous communication beam to a first receiver at a first frequency; transmitting the second communication signal over a second continuous communication beam to a second receiver at the first frequency; receiving the first communication signal at the second receiver; estimating a first channel response for the first communication signal received at the second receiver; sending information regarding the first channel response back to a transmitter; and further comprising: a pre-coder on the transmitter side modifying the first communication signal by passing said first communication signal through a first filter, the first filter having coefficients optimized for cancellation of said first communication signal received at said second receiver, the coefficients being based, at least in part, on the information regarding the first channel response; and an adder adding said modified first communication signal to said second communication signal.
