英文摘要： The enhancement of wireless network communication performance has always been the focus which is widely concerned in academia and industry. According to Shannon theorem, the communication rate is limited by its bandwidth and SNR of channel. Most recent researches based on OFDM, MIMO etc. are committed to improving SNR of channel, or optimizing the efficient of transmission to enhance the wireless communication performance. And the magnitude of enhancement has its restriction. This application start from breaking through the wireless network communication performance restrictions on fixed bandwidth, explores a new mechanism that take advantages of scalable bandwidth wireless channel to enhance the wireless communication performance, design a scalable frame of wireless communication, provides innovative ideas on new generation wireless communication process. For the limitation that wireless terminal works under the fixed bandwidth, Scalable bandwidth wireless signal processing technology implemented in using fixed and limited bandwidth wireless communication terminals is proposed innovatively, and technical solutions of hyper-wideband wireless signal processing are elaborated. For the requirements of high-performance hyper-wideband wireless signal computing, array-based scalable computing frame is designed. The anticipated achievements of this application are expected to provide original innovative technological breakthroughs for high-performance wireless communication. It has important theoretical significance and application prospects.
