Description

technical field [0001] The invention relates to the field of electronic information, in particular to an infrared wireless sending device. Background technique [0002] In the transmission system, a CP obtained by duplicating a predetermined part of the rear end of a data block is added to the head of a data block, and the length of the CP attached to the survival signal is set to be longer than between terminals that simultaneously transmit at different frequencies The propagation delay difference and the delayed waves generated on the multipath. When there is a delayed wave exceeding the CP length, FFT processing units will be generated, which easily leads to deterioration of reception quality. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the above-mentioned problems, an infrared wireless sending device is provided, which has a reasonable design structure and can improve the sending quality.
