Clock analogy Phase can be proportional to time, If the frequency is constant and the initial phase is zero, then the phase of a sinusoid is proportional to time. Source: Internet
The integral of such a signal is: : In this case, the expression for y(t) above simplifies to: : where the amplitude of the modulating sinusoid is represented by the peak deviation (see frequency deviation ). Source: Internet
The reason that the guard interval consists of a copy of the end of the OFDM symbol is so that the receiver will integrate over an integer number of sinusoid cycles for each of the multipaths when it performs OFDM demodulation with the FFT. Source: Internet
