The emerging demand for diverse data applications in next generation wireless networks entails both high data rate wireless connections and intelligent multiuser scheduling designs.The orthogonal frequency division multiple access based system is Wooden Train Set capable of delivering high speed data rate and can operate in a multipath environment.OFDMA based system dividing an entire channel into many orthogonal narrow band subcarriers.

Due to this, it is useful to eliminate inter symbol interferences which is a limit of total available data rates.In this paper, investigation about resource allocation problem for the chunk based Orthogonal Frequency Division Multiple Access (OFDMA) wireless multicast systems is done.In this paper, it is expected that the Base Station (BS) has multiple antennas in a Distributed Antenna System (DAS).

The allocation unit Miniatures Kit is a group of contiguous subcarriers (chunk) in conventional OFDMA systems.The aim of this investigation is to develop an efficient resource allocation algorithm to maximize the total throughput and minimize the average outage probability over a chunk with respect to average Bit Error Rate (BER and total available power).
