Can we prefexdo cyclic prefix with zerozeros in ofdmOFDM rather than with samples from end of the ofdm symbol?

considering an ofdmOFDM symbol of x(0)x(1)x(2)x(3)x(4)....x(n-2)x(n-1)x(n), to. To perform cyclic prefix we prefix some samples from end of this ofdmOFDM symbol to the beginingbeginning of the ofdmOFDM symbol, like like

x(n-3)x(n-2)x(n-1)x(n)x(0)x(1)x(2)x(3)........ x(n-4)x(n-3)x(n-2)x(n-1)x(n).

Instead of taking x(n-3)x(n-2)x(n-1)x(n), if we prefix with zeroeszeros what will happen?
