system need to cope the problemS how to increase the number of user and services that are supported in limited radio frequency bandwidth in define area. This requirement can be achieved if system design engineers overcome the problem of bandwidth efficiency by increasing the data transmission rate and capacity to use multi-level modulation and demodulation‚ instead of increasing the radio frequency bandwidth. Higher data rate can be achieved from 100Mbps to 1Gbps. Low transfer delay time to 50ms or

fading is deviation of the attenuation affecting a signal over certain propagation media. The fading may vary with time‚ geographical position or radio frequency‚ and is often modeled as a random process. A fading channel is a communication channel comprising fading. In wireless systems‚ fading may either be due to multipath propagation‚ referred to as multipath induced fading‚ or due to shadowing from obstacles affecting the wave propagation‚ sometimes referred to as shadow fading. The presence
