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.
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.

Loss Of OFC communication is this technology is very expensive.

Stability in business means that your income is continuously growing and you are not going in to loss. These days it is very difficult to achieve the stability in market due to competition and rapid progress in technology.
Net Income zero means firm has at no profit no loss position and it does not means loss to company.

Akinesia means loss of movement. Rigor means rigidness preventing response to stimuli - also a loss of movement.
Some of the pros of licensing technology are that the owner shares in any technological improvements and receives technical assistance. Cons include loss of control over the product and loss of intellectual property.
indifference to loss it means for example in the classroom ,should be attentive to the stadium,and do our duty in the calssroom ,and here is not exposed do loss and loss.
Progressions in technology has stimulated great economic debate as the need for human labour is being increasing replaced by capital equipment. The fundamental underlying nature of the concept is that as machines are able to create other machines, the need for human workers is lessened, and consequently, technology leads to loss of jobs.
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’.
The word "dehydration" means loss of water, from the Greek root hydro (water).
