Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a multi-tap interference elimination device and system. Background technique [0002] In recent years, with the continuous development of mobile communication technology, data services have grown exponentially. Such rapid data growth has brought enormous pressure to the entire wireless access network, and the system capacity and spectrum efficiency of the wireless network need to be improved urgently. However, existing wireless communication systems usually use time division duplexing or frequency division duplexing to realize data transmission and reception, and cannot realize simultaneous transmission and reception at the same frequency end. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-tap interference elimination device and system, which can solve the problem of halving the spectrum utilizat...
