摘要
实现低误码率无保护间隔的数据传输可有效降低信息冗余度,对节省系统带宽和提高数据率意义重大。将隐形训练序列直接加入传输数据中消除保护间隔,推导循环相关信道估计算法后再进行剪贴式的干扰消除,仿真分析了不同信道估计方法的性能,结果表明本算法可兼顾系统性能和计算复杂度。
Data transmission of low BER（ Bit Error Rate） without GI（Guard Interval） can effectively reduce the information redundancy and is important to save the band of system and raise the data rate. IT（ Implicit Training） is added to data directly to cancel the GI. The interferences are canceled by cutting and pasting after the circular correlation channel estimation algorithm is deduced. Comparison between different channel estimation algorithms shows that the new algorithm has acceptable performance and low complexity.
