Abstract :
In this present work, we have studied multipath effects on wireless mobile communication. The multipath effect is most significant when the data rate is very high. Two different solutions to the multipath problem are suggested in the present work. The frequency diversion technique provides a solution, but for very high data rates the COFDM technique is a better solution.
