In_____, the highest-power signal is demodulated to estimate its bitstream.

(a) maximum likelihood

(b) sequential interference cancellation

(c) least mean square

(d) recursive least square

I have been asked this question by my college director while I was bunking the class.

This key question is from Smart Antenna topic in chapter Smart Antenna & Software Component Characteristics of Cognitive Radio

The correct choice is (b) sequential interference cancellation

To explain I would say: In sequential interference cancellation, the highest-power signal is demodulated to estimate its bitstream. By employing this technique, co-channel interference from strongest interferer can be reduced substantially.
