49687 为克服传统盲源分离抗干扰方法需要多副接收天线这一技术瓶颈，提出一种单通道下基于扩频码周期性的直扩通信半盲分离抗干扰算法。 In order to overcome the traditional blind source separation anti-interference methods need more pair of receiving antenna this technical bottleneck, put forward a kind of single channel based on spread spectrum code under periodic spread spectrum communication anti-jamming algorithm half blind source separation.
49688 该方法基于扩频码的周期性，利用符号级过采样，把单通道多径慢衰落信道模型转化为多通道瞬时混合模型， Periodicity of the method is based on spread spectrum code using symbol level sampling, the single channel multipath slow fading channel model for the channel instantaneous hybrid model,
