Method and apparatus for real-time adaptive interference cancellation in dynamic environments |
March 18, 1997 |
| A finite impulse response filter performs an FFT on a signal, multiplies it by a transfer function in the frequency domain, and then performs an inverse FFT. The transfer function is dynamically computed in real-time by detecting signal energy in the frequency domain and turning off bins |
