An improved spectral efficiency of WiMAX using 802.16G based technology

WiMAX (World Wide Interoperability Mobile Access) is commonly known as IEEE 802.16 Standard. The WiMAX provides an amends for the broadcast services and broadcast content feeder network. All these services depend on the primary use of frequency band. Many technologies can be deployed with the frequency band of about 2.4 GHZ, 3.5 GHZ and 5 GHZ. The MIMO (Multiple Input and Multiple Output) uses multiple transmitter and receiver antenna at the transmitting and receiving terminal and hence which is known as Smart Antenna, high range possibility. The OFDMA (Orthogonal Frequency Division Multiple Access) divides the channel into eight orthogonal sub channels and uses subcarrier on each subchannel for modulation. At peak points the OFDMA has average power for transmission of data. So we explore our work 802.16g protocol which overcomes the problem with 802.16e protocol.
