Question

What is the full form of CE-OFDM?

a.

Closed Envelope Orthogonal Frequency Division Multiplexing

b.

Constant Envelope Orthogonal Frequency Division Multiplexing

c.

Constant Evolute Orthogonal Frequency Division Multiplexing

d.

Closed Evolute Orthogonal Frequency Division Multiplexing

Posted under Cognitive Radio

Answer: (b).Constant Envelope Orthogonal Frequency Division Multiplexing Explanation:In Constant Envelope Orthogonal Frequency Division Multiplexing, the complex modulated signals are positioned in a complex conjugated arrangement to obtain a real value inverse fast Fourier transform output. Also, phase modulation is applied in the real value time domain. This technique reduces the high peak to average power ratio of OFDM.
