The analysis and research of adaptive transmission algorithms in wireless communication system

The next generation wireless communication system requests to have higher transmission rate and better deliver quality, and request to have a higher coefficient of utilization of frequency. OFDM has been regarded as a key technology for high data rate transmission in wireless channel. Adaptive transmission techniques can dramatically raise the spectral efficiency, reduce interference and improve the communication quality of wireless communication system, and cause more and more concern of people. So this paper analyses and compares adaptive transmission algorithms based OFDM according to simulation, and designs an adaptive transmission wireless communication system based on OFDM by using simple block loading algorithm (SBLA).
