Performances of Zigzag coding with high-level modulations on WiMAX system

The WiMAX which is a technology of OFDM base provides wireless communication from one-point to multi-point. In this study, for fixed and mobile WiMAX systems performance analysis of different modulation types and Zigzag encoder schemes is investigated. One of the important advantages of the error correction codes has no need re-transmission of data packets. The results of proposed Zigzag-coded modulation show that they have a good performance at least other techniques.
