MUltiuser Orthogonal Frequency Division Multiplexing (MUOFDM) is one of the promising techniques for future cellular and wireless networks for achieving high downlink capacities. The objective of the next generation cellular and wireless networks, which are based on (MU-OFDM) is to increase the network efficiency by maximizing the total throughput of the system and minimizing the overall transmit power for a given Quality Of Service (QOS). The sum capacity of MU-OFDM is maximized when each sub-channel is assigned to the user with the best channel to noise ratio for that sub-channel. Ever increasing demand for high throughput, low delay and low Outage probability can be met by using Adaptive Resource Allocation in OFDM Technology.
