AB  - Now a days the wireless communication plays an important role 
  in various fields such as business, entertainment, information processing, etc. 
  There are various methods of modulation schemes which are used to send and receive 
  the data to or from the base station and mobile stations. The 4G wireless communications 
  are used in various applications such as multimedia, live streaming, video conferencing, 
  mobile TV and so on. The OFDMA (Orthogonal Frequency Division Multiple-Access) 
  techniques are used to support multiple users who can communicate with the single 
  base station to improve the throughput. MIMO (Multiple Input Multiple Output) 
  is a technique which is used to satisfy the demand of the wireless communication 
  system. The channels are allocated to the user for efficient communication between 
  base station and mobile stations. The channel with minimum transmission power 
  has been assigned to the user from the channel list. Suppose the requested channel 
  is not available which leads a performance problem then the channels are maintained 
  as a group. The proposed technique maintains a group of channel in an increasing 
  order. Suppose the channel unavailability occur it will select a suitable channel 
  from the group. If the requested channel is not available in the group it will 
  automatically select a channel from the other group which decreased the signal 
  to noise ratio in the communication. It also uses various algorithms like channel 
  and group estimation, channel assignment and alignment which improve the throughput 
  over the wireless communication. The adaptive technique also implemented to 
  assign and align the channel to the requested users. In future the throughput 
  will be improved by using an efficient technique.
