摘要： The present invention provides a wireless transmission method and system based on maximum multi-path delay estimation. A wireless transmission method based on an estimation of maximum multi-paths delay, comprising: a communication apparatus involved in wireless communication estimates the maximum multi-paths delay of a currently received frame; the communication apparatus performs a quantization and coding on feedback information related with the estimated maximum multi-paths delay, and then sends the feedback information which has been subjected to the quantization and coding to an opposing communication apparatus which is in wireless communication with the communication apparatus; the opposing communication apparatus recovers the feedback information by demodulating and decoding the feedback information which has been subjected to the quantization and coding; 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 that sufficiently improves the spectrum utilization efficiency of wireless resources (the throughput is increased by about 5%).
