The cyclic prefix is intended to be long enough to mitigate the majority of expected multipath. In LTE CP durations are 4.7 usec. Since multipath comes from signals traveling longer distances than that of the shortest path signal. If the shortest path between Tx and Rx is 1km, what is the distance of the longest traveled multipath signal I f the multipath delay should be significantly less than the CP duration (use factor of 10)
