摘　　要：提出了一种基于LDPC码的物理层包编码方法。在该方法中,通过建立多个码块特定位置上简单异或关系,使得任何一个码块在译码过程中、在该特定位置上从其他码块获得一份额外的边信息,并且译码过程中还引入了类似码字串行干扰抵消(SIC)接收机的思想。该方法具有性能增益明显,复杂度低,接收延迟小,克服突发差错好等优势,非常适合未来5G的应用场景。In this paper, we propose a physical layer packet coding method based on low density parity check codes（LDPC）. By establishing the simple XOR relationship on specific position of multiple codes blocks, any code block in the specific position can get additional extrinsic information from other code blocks in the process of decoding, and the idea of serial interference cancellation（SIC） receiver is also used. This method has many advantages, including obvious performance gain,low complexity, low receiving latency and well performance on combating burst errors, and is very suitable for the future 5G application.
