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.
What else can I help you with?
Explain ICI in ofdm systems?
Multi Carrier systems like OFDM has the problem of Inter Carrier Interference(ICI), which results from the loss of Orthogonality between the sub carriers.This happens when the FFT is considered over duration where the subcarrier is non integer number of cycles, which would be the case when multipath is present and the guard time has amplitude is zero.This is reduced by use of cyclic prefix, where we transmit a copy the last part of the symbol followed by the symbol itself.This ensures Orthogonality over the FFT period in case of delayed multipath. yup...that's all from me. Regards Girish .V.V There are many methods to reduce ICI not only CP like Frequency domain equalization,Time domain windowing,Pulse shaping,Maximum likelihood estimation,Extended kalman filtering and ICI self cancellation.And any one have their own advantages.

What are effects of load shedding on industries?
Loss of production: where most industries use electricity for machinery, technology and light to complete the day’s work, loss of electrical power means that the day’s target cannot be completed. Loss of profit: with the loss of production, there is a loss of profit, and in some cases, a large loss. Industries cannot keep pay their employees to be present during a power outage as essentially they will be paying a ‘non-worker’.
