For basis function generation algorithm of the traditional MIMO-TDCS based on binary adjudicate have the problem of reflecting the difference of channel quality inaccurately,a kind of MIMO-TDCS based on adaptive multi-threshold algorithm for basis function generation is proposed.The theoretical analysis shows that the algorithm of basis functions generation based on adaptive multi-threshold can overcome the shortcoming of the traditional binary adjudicate threshold algorithm of bad adaptability and reflecting channel quality inaccurately.It allocates power of signal depending on the difference of channel quality and make power allocation more reasonably,so it can improve the performance of bit error.The simulation results show that the system is a kind of available communication technique which has strong anti-interference ability.
