ABSTRACT:
A radio sensitivity enhancer inputs an incoming radio frequency signal into two receiver strings. The first receiver string modulates the RF signal to a frequency which is passed by a filter to produce the desired signal plus a noise component. In the second receiver string, the RF signal is modulated to a frequency outside the frequencies passed by a filter to produce a signal with a noise component but without the desired signal. The desired signal with the noise component is then subtracted from the signal with only the noise component to produce a substantially noise-free desired signal.
