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 digital communication link; and producing a second communication signal for a second digital communication link; characterized by: producing a modified first communication signal by: producing a first filtered signal by filtering the first communication signal using a first M-tap Finite Impulse Response filter with coefficients optimized for transmitter interference cancellation; and producing a second filtered signal by filtering the second communication signal using a second M-tap Finite Impulse Response filter with coefficients optimized for transmitter interference cancellation; and combining the first filtered signal and the second filtered signal; transmitting the modified first communication signal over a first continuous communication beam at a first frequency; and producing a modified second communication signal by: producing a third filtered signal by filtering the second communication signal using a third M-tap Finite Impulse Response filter with coefficients optimized for transmitter interference cancellation; and producing a fourth filtered signal by filtering the first communication signal filtered using a fourth M-tap Finite Impulse Response filter with coefficients optimized for transmitter interference cancellation; and combining the third filtered signal and the fourth filtered signal; transmitting the modified second communication signal over a second continuous communication beam at the first frequency. producing a first communication signal for a first digital communication link;
