What is 'ofdm'?

Orthogonal frequency-division multiplexing

What does the term 'phase noise' means?

Phase noise is a measure of randomness in a data set or frequency. It is often seen as short, random and rapid fluctuations which happen within a waveform.

What is OFDM training symbol?

Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital. Pilot signals and training symbols (preambles) may also be used for time.

Where the phased locked loop is used?

Phase lock loop is used in analog and digital communications to keep the phase of the output signal the same as the input signal.

What is the frequency range used in wireless communication?

2.4GHz is used & OFDM

What is loss of orthogonality means in OFDM technology?

In OFDM, sub-carrier spacing is maintained in such a way that the maximum of one sub-carrier occurs at the minimum of the successive sub-carrier, a loss of orthogonality results if this pattern is not achieved in the sub-carriers of OFDM transmission. Loss of orthogonality is due to ISI, ICS, Frequency offset amongst the sub-carriers of OFDM.

How you eliminate inter symbol interference in ofdm?

Inter symbol interference (ISI) in OFDM systems can be minimized by using a cyclic prefix. This involves adding a copy of the end of each OFDM symbol to the beginning before transmission. The cyclic prefix helps to mitigate the effects of multipath fading and reduces ISI by allowing the receiver to separate the OFDM symbols with a guard interval.
