Abstract This paper focuses on the anti-interference technique to restrain the interfer-ence of co-channel users while simply introducing the concept of space-time block coding. Anti-interference technique uses the relationship among signals to remove the interference, which can enhance the capacity of communication system by introducing co-channel users. Moreover, the paper submits a strategy to eliminate the effect of co-channel interference by decoding signals by stages while using different performance of various modulation tech-niques. The system performance can get more enhancements by using this strategy, which is very important for enlarging the capacity of system.
