SYSTEM AND METHOD FOR COMMUNICATING AT LOW SIGNAL-TO-NOISE RATIO USING INJECTED TRAINING SYMBOLS
摘要：
A system and method for communicating includes a transmitter that transmits a communication signal having a plurality of successive frames, with each frame formed with alternatively arranged N known data symbols and M unknown data symbols such that the N known data symbols as training symbols. The communications signals are received within a receiver. The N known data symbols are synchronized at the receiver by correlating and time averaging the N known data symbols.
摘要（中）：

用于通信的系统和方法包括发送具有多个连续帧的通信信号的发射机，其中每个帧由备选地布置的N个已知数据符号和M个未知数据符号形成，使得N个已知数据符号作为训练符号。 在接收机内接收通信信号。 通过对N个已知数据符号进行相关和时间平均，N个已知数据符号在接收机处被同步。
