Adaptive transmission method and system for wireless communication system

摘要

The present invention provides a wireless transmission method and system based on maximum multi-path delay estimation. The method comprises: a communication apparatus involved in wireless communication estimating the maximum multi-path delay of a currently received frame; the communication apparatus performing quantization and coding on feedback information related to the estimated maximum multi-path delay, and then sends the result to an opposing communication apparatus; the opposing communication apparatus recovers the feedback information by demodulation and decoding; the opposing communication apparatus performs an adaptive adjustment of wireless signals transmitted to the communication apparatus, based on the recovered feedback information. With this method, system parameters can be adaptively adjusted so as to improve the spectral efficiency.
