Which among the following is achieved by coupling a modulated signal with a sine wave carrier?(a) Causality(b) Periodicity(c) Linearity(d) StabilityThe question was asked in unit test.My question is from Next Generation Wireless Network topic in chapter Next Generation Wireless Network of Cognitive Radio

Answer»

Correct CHOICE is (b) Periodicity

To elaborate: MODULATED signals are coupled with sine WAVE carriers, hopping sequences, or cyclic PREFIXES to attain periodicity. The signals are regarded as cyclostationary due to periodic mean and AUTOCORRELATION.
