Abstract

Achieving the improved digital communication systems with the cancellation of Non-Linear Distortion Noise is difficult task. Transmitting the digital video broadcasting through air interface through the interleaved Frequency- division multiple access scheme is possible. The comparative study is need to be done with the consideration of single carrier frequency division multiple access schemes and orthogonal FDMA schemes with the satellite uplink. The High Power Amplifiers should be operated in the K Band and S Band. The multiuser environment has to be developed to demonstrate the performance of synchronous and asynchronous LFDMA, IFDMA and OFDMA. The performance results of the Frequency Division Multiple access should be evaluated. In fact the Iterative Frequency Division Multiple Access is regarded as the outperforming scheme. The Inter Block Interference is causing the most sensitive degradation for asynchronous reception. To achieve the non-linear distortion in the large envelope fluctuations OFDMA is regarded as the best scheme among the other schemes like IFDMA and LFDMA. The proposed paper is focusing on the OFDMA performance and its better advantages in comparison with other schemes. The main aim of the paper is to suggest the best technique to reduce the linear and non-linear distortion in Integrated Terrestrial and Satellite Systems.
