Satellite communication interference cancellation method for large-capacity access

The invention relates to the field of communication, discloses a satellite communication interference cancellation method for high-capacity access, and aims at solving the problem of interference cancellation under the conditions of real-time service processing and limited satellite-borne resources in satellite communication by adopting a method for constraining an interference cancellation weight of a multi-user signal by searching a minimum value of a quadric surface of a Virnahoff equation. During de-spreading, the multi-user interference is quickly eliminated, and the satellite communication interference elimination efficiency is improved. Compared with a traditional satellite communication interference cancellation technology, the method has the advantages of being short in time delay, low in resource consumption, easy to transplant and popularize and the like. 本发明涉及通信领域，公开了一种用于大容量接入的卫星通信干扰对消方法，针对卫星通信中实时业务处理和星载资源受限条件下的干扰消除问题，采用搜索维纳霍夫方程二次曲面的最小值来约束多用户信号的干扰抵消权值的方法，在解扩的同时，实现多用户干扰的快速消除，提升卫星通信干扰消除效率。本发明相对传统的卫星
